I have a Tube Factor that I would like to leave back with the amp. It has a remote switch for a TRS pedal to switch it on/off and between the two gain stages. I don't really want to buy the H&K remote switch because it is fifty bucks and I see a lot of generic pedals out there for less than half that. For example, two button Marshall replacement pedals for channels and reverb. Would it be safe to assume that any two button TRS pedal will work as long as it is latching? Oddly enough I don't have one around to test it out. Thanks!
