The amp has a clean section and a drive section.
When you're in the drive section you can select drive p- indicated by a yellow light (which is still pleasant)

and more drive - indicated by a red light (which is too messy for my liking)
I have a pedal which switches between two. It's an old Crate pedal with places for two jack plugs but the amp only has one, and it works OK... kind of.
drive...
The problem is that when the pedal switches for clean to lead channels, it bypasses the 'drive' section (yellow light) and goes straight to the 'more drive' section (red light)
I brought home another pedal form the local guitar shop... Hi-Watt with two stereo jack plugs, and it does nought.
I'm wondering if there izzent an easy quick fix solution to this problem, like clipping a wire so that the foot switch brings only the drive section and not the more drive section...
Problem is I dunno what um doing... if it was a bomb I'd likely clip the blue wire and blow myself up :-[
