I own a Stone Bender but didn't really try it out thoroughly until recently. Anyway, since there's the option to mess with internal trim pots, I did. Now I can't seem to get a great sound out of it at all. Good, but not great. And the pots are back to their original settings. The bias isn't right and sounds too velcro-y. I can't get as much sustain as I want. I see a lot of positive comments about this pedal here and I'm wondering what folks are using it with (guitar, amp, etc.). I have a number of fuzz pedals and haven't had this problem before. I'm running it through a stock Blues Jr. and using humbuckers. I read somewhere here that running it through a dirty Marshall is the way to go, but all the fuzzes I have (and there are many...even other benders) have sounded fine through my clean Fender. Any comments, suggestions, etc. will be greatly appreciated!
