While the Overdrive 202 is Quilter footswitch compatible, only three of the effects on our footswitches will work on this amp, which are the following:
1. CH 1/2 (to switch between the Clean and Overdrive channel)
2. Limiter
3. Reverb
The three other controls of the UFC-3 (or any of our discontinued footswitch models) are not applicable to the OD202:
1. Boost
2. Tremolo
3. FX Loop (the FX Loop of the OD202 is always active and doesn't need to be engaged)
So if you engage one of these effects on your footswitch, it will basically do nothing to the amp, as the OD202 does not contain these features
