2. Navigating Presets and Effects
The TANK-PRO comes with 120 presets (60 factory, 60 user). Use footswitches A and D to bank up/down through presets. Short-press footswitches B and C to toggle individual effects within a preset (STOMP mode) or to switch between LIVE and CTRL modes.

3. Using the Looper
The integrated looper allows for up to 150 seconds of stereo recording. To activate the looper, press the LOOP footswitch (often footswitch B, depending on mode).
