4. Operation Guide
4.1. Footswitch Functions
The Tank-G features four footswitches: A/REVERB, B/DELAY, C/MOD, and D/AMP.
- A/REVERB, B/DELAY, C/MOD: These footswitches activate or deactivate their respective effect blocks (Reverb, Delay, Modulation) within a preset.
- D/AMP: This footswitch typically controls the amplifier model or a specific function like a boost.
- BANK - / BANK +: The footswitches also serve as bank navigation. Pressing the left footswitch (A/REVERB) and the right footswitch (D/AMP) simultaneously allows you to cycle through banks of presets.
- LIVE/PRESET (Hold Tuner/BT): This central button/display area allows switching between Live mode (individual effect control) and Preset mode. Holding this button activates the built-in tuner or Bluetooth pairing.
4.2. Adjusting Effects Parameters
The top row of knobs allows for fine-tuning of various effect parameters:
- MASTER: Overall output volume.
- IR CAB: Adjusts parameters related to the Impulse Response cabinet simulation.
- RVB MIX, RVB DECAY: Controls for Reverb effect.
- DLY MIX, DLY TIME: Controls for Delay effect.
- MOD SPEED, MOD FX: Controls for Modulation effects.
- VOLUME, BASS, MIDDLE, TREBLE, GAIN, TYPE: Controls for the amplifier section, including volume, 3-band EQ, gain, and amplifier type selection.
- NOISE GATE: Adjusts the threshold of the noise gate.
4.3. Using Presets
The Tank-G comes with 36 editable presets. You can navigate through these presets using the BANK - and BANK + functions of the footswitches. Each preset stores a complete chain of effects and their settings.
