I know this amp isn't exactly "well-loved" around here, but I've had one since 1998, and have generally had pretty good luck with it. I've gigged it, and beat it to death for over a dozen years, and it's still basically going strong. (Although the footswitch hasn't worked in years .) Anyway, I use the middle gain channel 99% of the time, and use a SHOD if I need any more gain than that. But I was wondering if there might be any benefit by pulling the preamp tubes on the clean or high gain channels? (Like they do on Deluxe Reverbs, pulling V-1 etc.) I think I was told in the past it would be OK to do. Any thoughts?
