MODE 2 - PRESETS (Preset Select & Bank UP/DOWN)

Note: Tap Tempo is NOT available in Effects or Looper mode.
MODE 3 - EFFECTS (Bypass effects)
- In this mode, each footswitch can be used to enable or bypass the first 3 available effects in the preset. The footswitch button LEDs indicate the effects that are active on the buttons labeled: FX 1, FX 2, FX 3 (in line with the EFFECTS LED).
MODE 4 - LOOPER
LOOPER mode enables the user to record loops up to 60 seconds long and overdub subsequent parts. Any number of overdubbed parts can be layered over the original recorded part; however, only the last overdub created can be undone.
1. Press the leftmost footswitch to select “LOOPER” mode
2. To begin recording the first musical passage, step on button labeled “REC/DUB.” The red FUNCTION LED above FUNCTION button 1 will begin flashing and the DISPLAY WINDOW will show “REC,” indicating that the LOOPER is in recording mode; play a passage of any time duration up to 60 seconds.
3. When finished playing, stop recording and automatically begin playback by stepping on button 2 labeled “PLAY/STOP.” The red LED above button 1 will stop flashing, the red LED above FUNCTION button 2 will illuminate, and the DISPLAY WINDOW will indicate playback by showing “PLA”. To stop playback, step on button 2 again; the DISPLAY WINDOW will show “StP”.
4. Alternately, when finished playing the first musical passage, step on button 1 again to go straight into overdub mode; the red LED above button 1 will continue flashing and the DISPLAY WINDOW will show “DUB,” indicating that the LOOPER is now in overdub mode and a second musical passage can be recorded over the first. Overdub mode can also be activated during playback or after stopping playback by stepping on button 1 again. Continue overdubbing musical passages as often as desired. After an overdub is recorded, step on button 2 to start and stop playback of all recorded parts.
5. While recording, playing back or stopped on the first musical passage, the user can undo the recording if desired by stepping on button labeled “UNDO.” Recording will stop and the DISPLAY WINDOW will read “STP”, and whatever had been recorded is now erased. Once overdubs have been added, however, the UNDO function applies only to the last overdub recorded; preceding overdubs cannot be undone.

- When a string is tuned LED directly under display screen will illuminate green.
- When a string is “Flat” LED above button 1 will illuminate red.
