I replace those with film caps whenever possible.

Peavey used electrolytic coupling caps IIRC in those amps and those can drift in value and ESR. They are far older than their design lifespan-electrolytics are notorious for drying out after several decades. Call GAK now for product info, advice and the Best Prices - 01273 665400. The interface can be used with any recording, processing, or tuning application, including Agile Partners' GuitarToolkit, one of the highest-rated applications in the iTunes App Store. One would be to recap that amp: replace ALL electrolytic capacitors. AmpKit LiNK is a powered device with circuitry that virtually eliminates feedback. However, you could still do some things that may help, and that you should probably do regardless.

Despite what some folks believe, the early Bandits were designed very well and didn’t cut a lot of corners, so if all it took was simply adding a cap to stop switching pops, I believe they probably would have put it in. Merely adding a capacitor somewhere might work but I suspect it could introduce other problems, depending on the circuit. Getting rid of those pops isn’t easy, and indeed that’s why amp manufacturers have used some more elaborate switching methods. It’s been a while since I went through the Bandit schematics but there are definitely several different Bandit circuits and they definitely didn’t use the same switching method throughout (although the foot switch itself was usually wired exactly as yours is). Peavey (like other amps) used several various schemes for channel/reverb switching, the simplest was actually routing the signal through the foot switch, another was the use of relays on the circuit board, yet another was the use of transistors to accomplish the switching. This is an issue for lots of amps, not just Peavey.
