I thought of this for the scrambler, but I've heard you can safely get a dirty sound from the amp. I'm a bit worried about trying it and how long I can do it for. I'm a bit wary of warning lights, flashing. That's more through ignorance than prudence. If you can help me with this effect, that'd be great. It's a PF-500 and I have PF115 and PF410 cabs.
