I have a Blackstar ID:60 TVP 60w amplifier that really doesn't have a whole lot of hours on it. I change the voice knob to something like "Super Crunch" and then strum my guitar, and it flickers between that channel and the "Crunch" channel. Or if I put it on "Crunch" it will flicker between that or "Clean Bright".
I'm not really sure what's going on here. It seems like something may have a bad connection somewhere. Has anyone ran into this problem? Likely not going to find any help on this, unfortunately, but it is worth a shot. Thanks.

what pickups in guitar do You have?

Slash's signature Seymour Duncan Alnico II Pro pups. Thinking it's a wiring issue with the guitar? I have multiples, I should try my Ibanez.

yes, as You described, it sounds like problem in wiring - too less output.
test on another guitar, need to have medium pickup output (~~10-12kOhm)

I'll give this a shot and see if it works.
