Installing the UAFX Control Mobile App

iOS

Search for and install “UAFX Control” from the App Store, or go here for direct links.

Important: When you open UAFX Control for the first time, iOS prompts you to allow Bluetooth. You must tap OK and allow Bluetooth to use UAFX Control. If you don’t, UAFX Control cannot connect to your UAFX pedals. To manually allow the app to use Bluetooth (if you choose Don’t Allow when prompted), open the Settings app, choose UAFX Control from the list, and enable Bluetooth.

uafx-control-mobile-allow-bluetooth.png

Android

Search for and install “UAFX Control” from the Google Play Store, or go here for direct links.

Important: When Android prompts you to access the device’s location, you must allow the device location. If you deny the location, UAFX Control cannot use Bluetooth, and will not be able to connect to your UAFX pedals.

Android Device Location Notes

  • Device location is an Android requirement that allows an app to use Bluetooth. Universal Audio does not use UAFX Control to track location in any way.
  • If you deny app access to the device location, you will need to remove and reinstall the app.
  • Your Android device may present a different dialog to allow location information.

Important Preset/Rig and Backup Notes

  • Pedal presets - Individual presets you see in the app are stored on the pedal, not in the app. If UAFX Control is disconnected from your mobile device, or if you delete the app, all presets remain on the pedal.
  • Pedal backups - Backups created in the mobile app are stored in the app, not on the pedal. If UAFX Control is deleted from your mobile device, the preset backups in the app are permanently lost.

Factory and artist presets

The first time you connect your pedal to UAFX Control, the app installs UA factory and artist presets onto the pedal. The factory and artist presets are read-only and cannot be modified, but after loading an artist or factory preset, you can adjust the pedal’s settings, then store it (using the pedal’s Store switch) as your own user preset.

Special features in factory and artist presets

Some factory and artist presets include features that are not accessible with the pedal controls. These features may include speaker cabinets, microphones, room changes, and effect configurations. These presets can also include custom control mappings, so knobs and switches might not work as expected.

Preset and voicing descriptions are available here. To see a description of each factory or artist preset and any custom settings within the UAFX Control app, tap ••• to view preset info. 

preset-custom-description.png

You can edit a custom factory or artist preset and save it as your own preset by holding down the pedal’s Store switch to make use of these custom settings. You can also save a copy from the preset info overlay, then edit the sound with the knobs and switches, and save it on the pedal by holding down the Store switch.

To configure a new sound with available, non-custom sounds and knob settings, switch to Live mode and save a new preset.

Viewing and selecting presets

To view and select presets, tap a category at the top of the screen (User, Factory, Artist, or Favorite).

  • User includes all presets you have stored on the pedal. Note that there are no user presets until you store them.
  • Factory includes presets made by UA sound designers as useful tonal starting points.
  • Artist includes presets made by select UA artists.
  • Favorite includes presets that you have swiped as favorites. Note that there are no Favorite presets until you favorite them.

To select a preset and load it into the Preset slot on the pedal, tap on a preset. The preset is immediately loaded and you can play through it to hear the sound.

Note: If the pedal is in Live mode when a preset is loaded, the pedal switches to Preset mode. If the pedal is bypassed, the pedal is unbypassed by the app.

To favorite a preset

Swipe a preset to the right to make it a favorite. To unfavorite a preset, swipe the preset to the right again. The preset is starred when it is a favorite.

Tip: You can also favorite a preset by opening preset options, then tapping Favorite.

To delete a preset

  • Swipe to the left to delete a User preset, then tap the X.

preset-swipe-delete.png

To store a preset

To store a sound as a preset on the pedal, hold down the Store toggle switch on the pedal until the Preset LED blinks rapidly.

Preset options

  • Tap ••• next to the active preset to open the preset options.
    preset-edit-dots.png
    preset-edit.png
  • To change the name of the preset, tap the pencil next to the name, and type the name for the preset, then tap Save. Note that factory and artist presets cannot be renamed.
  • To favorite or unfavorite a preset, tap Favorite or Unfavorite.
  • After you load a preset, you can edit it by changing the knob and switch settings. When a preset has been changed, the EDITED label appears next to the name in the preset list.
    preset-edited.png
  • To save the preset, hold down the pedal’s Store switch until the Preset LED blinks rapidly. The preset is saved with a generic name (for example, “Dream 5”) to the User Presets list.
  • To save a copy of the preset, tap Save A Copy. A preset with the same name, and “Copy” appended, is saved to the top of the User list.
  • To delete a preset tap Delete, then tap Confirm Delete when prompted. You can also swipe a user preset in the User and Favorite lists to the left to delete. Note that factory and artist presets cannot be individually deleted.
  • Deleted user presets can be restored using the app’s backup/restore features.

Preset Notes

  • You can only save a new preset to a pedal by holding down the Store switch on the pedal, until the Preset LED blinks rapidly.
  • The following global settings can make presets on your UAFX pedal appear as edited, if the global settings are different than when the preset was saved:
    • 4-cable mode (Dream '65, Ruby '63, Woodrow '55)
    • Preamp coloration mode on/off (Starlight)
    • Tap tempo on/off (Astra, Starlight)

 


 

Backing up Presets and Rigs

Presets/Rigs Backup retrieves all user presets from the UAFX pedal and saves them as a single batch in the UAFX Control app. You might want to do this before you reset your pedal or before you delete presets or Rigs to maintain a copy of the current state. The backup is retained in the app even after you reset your pedal, so you can restore presets or Rigs at a later time.

Important: If you delete the UAFX Control app from your mobile device, your backups are permanently lost.

To back up your presets/Rigs

  1. At the bottom of the UAFX Control app, tap Settings.
  2. Scroll down if needed, then tap Save New Backup.
    backup-save.png

The backup is stored in the UAFX Control app.

Updating the backup

You can update the backup before you apply a firmware update or reset your pedal, or after you have changed presets or Rigs (storing, adding, deleting, and renaming) and you want to replace your backup to store the current state of your pedal presets or Rigs.

Important: When you update the backup, the pedal’s previously saved backup in the app is overwritten and permanently lost.

To update your backup

  1. Tap Update Backup.
    backup-after-backup.png
  2. In the warning popup, tap Update.
    update-backup-warning.png

The backup in UAFX Control is replaced with the presets or Rigs from the pedal.

Restore Backup

When you restore a backup from the app to the pedal, you have the option to either Replace Presets/Rigs or Merge Presets/Rigs.

  • Replace Presets/Rigs – All presets or Rigs on the pedal are deleted and replaced with all presets in the backup.
    Important: User presets or Rigs on the pedal that are not in the UAFX Control backup are permanently lost
  • Merge Presets/Rigs – All presets or Rigs in the UAFX Control backup are added to the presets or Rigs on the pedal. Note that merge can result in duplicate user presets and Rigs, because presets or Rigs with the same name are added and not replaced.

To restore your presets/Rigs

  1. In the Preset Backups section, tap Restore. The Restore options appear.
    backup-restore-info.png
  2. Tap Replace Presets/Rigs or Merge Presets/Rigs.

The presets or Rigs are restored to the pedal.

 

Viewing and restoring presets/Rigs from another pedal

If you connect two pedals of the same type to UAFX Control on the same mobile device, and save backups from both pedals in the app, UAFX Control allows you to restore the user presets or Rigs from one pedal to another.

To restore presets/Rigs from another pedal

  1. In the Preset/Rigs Backups section, tap the pedal backup from which you want to restore.

Resetting your UAFX Pedal

Reset your pedal to restore your UAFX pedal to the factory defaults.

Important Notes:

  • You must remove the pedal tile from UAFX control, and remove the pedal from your phone’s Bluetooth settings if you want to reconnect your mobile device after you reset the pedal defaults.
  • Resetting your pedal deletes any user presets, bonus speaker cabinets, bonus effect(s), and registration. Customized preset settings are permanently lost. (You can backup and restore your presets after you reset the pedal).
  • To get the bonus speaker cabinets or bonus effect(s) after resetting the pedal, register the pedal again with UAFX Control software.

To reset the pedal:

  1. Tap the Reset Pedal button at the bottom of the UAFX Control screen.
    reset-pedal-button.png

    reset-pedal.png
  2. Read the warnings, then tap Reset Pedal to continue. The pedal restarts.
  3. Remove the pedal tile from the UAFX Control app.
  4. Remove the pedal from your phone’s Bluetooth settings.

 


 

Live/Preset Switch

Note: Live and Preset modes are available only on Astra, Dream ‘65, Golden, Ruby ‘63, Starlight, and Woodrow ‘55.

You can choose to listen to the preset sound or the live sound with the app, instead of using the pedal’s footswitch. After you use the app to change to any footswitch mode except the default Live | Preset mode (in any mode that requires the pedal sound to be always on), you can choose whether the Live sound or the Preset sound is active.

Assigning the preset or live sound

At the bottom of the app, tap the Live/Preset buttons to switch between the live and preset sounds. Your choice will persist on the pedal until you switch to another sound, either with a footswitch on the pedal or with this switch in the app.

uafx-control-live-preset-slider.png

Important: This setting is retained when the pedal is powered off. This means that, when the active footswitch mode doesn’t allow switching between Live and Preset modes:

  • You won’t be able to switch between Live mode and Preset mode without the mobile app, and
  • You won’t be able to tell by looking at the pedal whether you’re in Live mode or Preset mode.

This circumstance applies to Ruby '63 and Dream '65 in the following modes:

  • Boost | Vibrato (Dream '65, Ruby '63)
  • Reverb | Vibrato (Dream '65)
  • Reverb | Boost (Dream '65)

Example 1

The footswitch mode is set to Boost | Vibrato and the app’s Live/Preset switch is set to Preset when the pedal is powered off. When the pedal is powered back on: the stored preset loads, the pedal is in Preset mode, and you can’t switch to Live mode without the app. This example allows your favorite sound (the stored preset) to always load as soon as the pedal is powered, but controls may not match the sound initially.

Example 2

The footswitch mode is set to Boost | Vibrato and the app’s Live/Preset switch is set to Live when the pedal is powered off. When the pedal is powered back on: the pedal is in Live mode, and you can’t switch to Preset mode without the app. This example ensures your knob and switch settings are heard when initially powered, but you can’t load the stored preset without the app.

Tip: To retain the ability to switch between Live mode and Preset mode without the app, set the footswitch mode to one of these values before powering off:

  • Live | Preset
  • Boost | Live/Preset
  • Vibrato | Live/Preset
  • Reverb | Live/Preset

 


 

4-Cable Mode (UAFX amp emulators only)

4-cable mode with Dream '65, Lion '68, Ruby '63, and Woodrow '55 amp pedals let you add another switchable channel to any real guitar amplifier that has an effects loop. This special mode lets you switch between your guitar amplifier’s built-in preamp section and the sounds in your pedal.

Warning: Turn off your amplifier before wiring the pedal and enabling 4-cable mode. If you enable 4-cable mode with incorrect wiring, you can cause extreme feedback.

How 4-cable mode works

  • When a UAFX amp pedal is on, the amp emulation is heard, and the real amp’s preamp section is bypassed.
  • When a UAFX amp pedal is off, the real amp’s preamp section is heard, and the pedal is bypassed with analog dry-through.

4-cable mode notes

  • 4-cable mode is only available on UAFX amp pedals (Dream '65, Lion '68, Ruby '63, and Woodrow '55).
  • If the pedal is not already in Live | Preset mode when you enable 4-cable mode, a confirmation appears, and the pedal automatically switches switches to Live | Preset mode after you confirm.
  • When you’re playing through a real guitar amplifier and speaker cabinet, you might want to disable the pedal’s speaker cabinet emulation by pressing the pedal's Speaker switch until its LED is unlit.
  • You may need to adjust the UAFX pedal’s Output knob lower than you normally would, because the effects loop return on your amp is unattenuated.
  • If you are using other pedals in your effects loop, place them between the first UAFX amp pedal’s 2/Stereo output and the Return input on your amp’s effects loop. With this wiring, the other pedals in the effects loop still process audio, even when the pedals are bypassed.
  • Front-of-amplifier effects, such as distortion and overdrive pedals, should be placed between the instrument and the first pedal’s 1/Mono input.
  • On Lion '68, Ruby '63 and Woodrow '55, the Room control does not have any effect in 4-cable mode.

Multiple UAFX amp pedals

To use multiple UAFX amp pedals in 4-cable mode, see the examples below. With multiple pedals configured in 4-cable mode, you can switch between preset and live sounds on the amp pedals and the sounds in your real amplifier for even more available sounds. When you use multiple amp pedals in 4-cable mode, the earliest amp pedal enabled in the chain is the amp pedal you hear.

Tip: To switch between sounds on different UAFX amp pedals with multiple pedals in 4-cable mode, enable sounds on multiple pedals. The first pedal that is enabled is the pedal you hear. When you bypass a pedal that is earlier than another enabled pedal, you will hear the next enabled pedal. In this way you can switch between sounds on multiple pedals.

To enable 4-cable mode

  1. Power off your real amplifier.
  2. Configure the cables as illustrated and described below.
  3. Connect to the pedal with the UAFX Control app, and open the pedal Settings screen.
  4. In the UAFX Control app, under 4-Cable Mode, tap On. A confirmation is displayed.
  5. Tap Enable 4-Cable Mode in UAFX Control. The pedal enters 4-cable mode.
  6. Turn your amplifier on.

You can now hear the UAFX amp pedal when Live mode or Preset mode is enabled, and your real amplifier’s preamp channel when the pedal is disabled.

4-cable mode connections

See the diagrams and sections below for 4-cable mode connections with one, two, or three UAFX amp pedals.

One UAFX amp pedal

Use 4-cable mode with one UAFX amp pedal to add another switchable channel to your real effects-loop equipped guitar amplifier.

  1. Connect your instrument to the 1/Mono input on your UAFX amp pedal.
  2. Connect the 1/Mono output from the UAFX amp pedal to the main input on your amplifier.
  3. Connect the effects loop Send output on your amplifier to the 2/Stereo input on your UAFX amp pedal.
  4. Connect the 2/Stereo output from the pedal to the effects loop Return input on your amplifier.
  5. Place any front-of-amplifier effects between your instrument and the UAFX amp pedal, and place any other effects loop effects between the pedal’s 2/Stereo output and the effects loop return input on your amplifier.

UAFX amp pedal enabled

This diagram shows the signal flow when the UAFX amp pedal is enabled. Your signal is colored with the full amp tone from the pedal and routed to your real amplifier’s effects loop return, bypassing your real amplifier’s input jack and preamplifier section. Any effects placed in your amplifier’s effects loop return are heard.

4-Cable-Active-Diagram.png

UAFX amp pedal bypassed

This diagram shows the signal flow when the UAFX amp pedal is bypassed. Note that your signal passes through the pedal with no pedal amp tone, and into the main input on your real amplifier. Any effects placed before your amplifier’s effects loop return are heard.

4-Cable-Bypass-Diagram.png

Two UAFX amp pedals

To connect two UAFX amp pedals in 4-cable mode, you need a total of six cables. Wire the pedals as described and shown in the diagram below. In this mode, the earliest enabled UAFX amp pedal is the one you hear, even when the other UAFX amp pedal is enabled. Looking at your pedals from the top, this would be the UAFX amp pedal furthest to the right. Any effects placed before your amplifier’s effects loop return are heard.

  1. Connect your instrument to the 1/Mono input on your first UAFX amp pedal.
  2. Connect the 1/Mono output from the first pedal to the 1/Mono input on the second pedal.
  3. Connect the 2/Stereo output from the first pedal to the effects loop Return input on your amplifier.
  4. Connect the 1/Mono output from the second pedal to the main input on your amplifier.
  5. Connect the 2/Stereo output from the second pedal to the 2/Stereo input on the first pedal.
  6. Connect the effects loop Send output on your amplifier to the 2/Stereo input on the second pedal.
  7. Place any front-of-amplifier effects between your instrument and the first UAFX amp pedal, and place any other effects loop effects between the first pedal’s 2/Stereo output and the effects loop return input on your amplifier.

6-Cable-Diagram.png

Three UAFX amp pedals

To connect three UAFX amp pedals in 4-cable mode, you need a total of eight cables. Wire the pedals as described and shown in the diagram below. In this mode, the earliest enabled pedal is the one you hear, even when one or both of the other two pedals are enabled. Looking at your pedals from the top, this would be the pedal furthest to the right. Any effects placed before your amplifier’s effects loop return are heard.

  1. Connect your instrument to the 1/Mono input on your first UAFX amp pedal.
  2. Connect the 1/Mono output from the first pedal to the 1/Mono input on the second pedal.
  3. Connect the 1/Mono output from the second pedal to the 1/Mono input on the third pedal.
  4. Connect the 2/Stereo output from the first pedal to the effects loop Return input on your amplifier.
  5. Connect the 2/Stereo output from the second pedal to the 2/Stereo input on the first pedal.
  6. Connect the 2/Stereo output from the third pedal to the 2/Stereo input on the second pedal.
  7. Connect the 1/Mono output from the third pedal to the main input on your amplifier.
  8. Connect the effects loop Send output on your amplifier to the 2/Stereo input on the third pedal.
