Using Effects from the Top Panel

Toggle On/Off

Press and hold any effect button. The LED lights up when the effect is on and breathes to indicate that it is selected for adjustment.

Select an Effect

Short press any of the six active effect buttons. The LED begins breathing, indicating that the Effect Level knob is assigned to that effect's primary parameter.

Adjust Parameters

Turn the Effect Knob to adjust the selected effect's Level, Mix, or Threshold (depending on the effect type).

For deeper parameter editing (e.g., delay time, reverb decay, chorus rate), use the Reactor App.

Signal Chain

All effect blocks can be freely rearranged in the signal chain via the Reactor App. The default signal chain order is:

Guitar In → Gate → Comp → Drive → Wah → EQ → [Amp] → Mod → Delay → Reverb → FX Loop → Output

The FX Loop can be inserted at any position in the chain, adjustable via the Reactor App.
