I have been searching youtube, here and other places for a sense of how the OCD plays with the AC15c1 stock. I like the amp without making any mods and I tend to use the TB channel. I specifically tend to use this as my bas setting: http://drpietrzak.com/music/AC15C1S.jpg . I play humbuckers, LPs, Washburn, CP Jag HH, etc. I am looking for a pedal that I can use for a grunty sound for rhythm work. I have tried a number of pedals and either have not hit the setting for the rhythm sound I want or just have not hit the right pedal. I have tried: DSL(v2), Thunderchief, Screw Driver, 69mkII, Lunar Module, Gainster, Les Luis, WF Rat, Huckleberry, Fuzzhead, and several others. I can get the sound I want from these pedals with other amps. It is just this amp-speaker I am trying to get this basic tone from now. I get close with several but ther eis a fizzy or harsh edge tot the top I am not liking. I know I could mod the amp, or use my others, but a 1 pedal addition here would be a great grab and go alternative for me. I was wondering how these pedals might do for the grunty gritty thing with this amp set up. OCD Plimsoul Box of Rock Plexitone Plexi-drive Maybe it is just he pedal settings I have tried so far ... Thoughts and ideas are welcome.
