Expression pedals allow you to control dynamic parameters like Wah or Volume on your REACTOR amp. Connect a standard TRS expression pedal to the EXP jack on the rear panel of REACTOR Control.
Expression Pedal Calibration
If your expression pedal does not respond accurately with REACTOR Control, calibrate it:
-
Enter Calibration Mode
Connect an expression pedal to the REACTOR Control. On the REACTOR amp, long press TAP + MOD buttons simultaneously (1 second) to enter calibration mode.
-
Record Toe Down Position
Top two FX LEDs (GATE, MOD) breathe white — push the pedal fully down (toe down), then short press TAP button to record. Top LEDs will flash white 3 times to confirm.
-
Record Toe Up Position
Bottom two FX LEDs (DRIVE, REVERB) breathe white — lift the pedal fully up (toe up), then short press TAP button to record. Bottom LEDs flash white 3 times — calibration complete.
