I'm looking for an overdrive ( fuzz / distortion / etc. ) to pair with my VT bass, and bartolini active pickups. A lot of the ones that I've tried in the past seem to sound better on passive electronics than on active. I really like the clips I've heard of the wolly mammoth, but have been reading that it dosen't sound very good with active pickups. I'm assuming that one of the mammoth clones being of similar design would have this same problem. Anybody out there have some knowledge to hit me with?
