anyone using processors ...,,,pls help . digitech rp 200 comes with both while rp 80 comes only with wah pedal ... thanks ...
No difference. The pedal on a multi-effects system is known as an "expression pedal" because it can be assigned/programmed to control more than 1 effect on the system. For eg, you program your multi-effects processor to have a reverb and a wah effect both in the chain. You can assign the expression pedal to the wah-effect, so that it becomes a wah-pedal, or you can assign it to control the reverb, in which case you could call it a "reverb-pedal". any multi-effect processor which offers wah as an effect and has an expression pedal can work as a wah-pedal.
