I know you fellas(and ladies... are there any ladies here?) are probably very tired of the distortion questions, but i've been reading a bunch of info and still have some questions. I use an all tube head (Mesa 400+), and use an active and a passive bass. Play mostly rock... from The Beatles to Black Sabbath to Grand Funk to Jane's Addiction to Kyuss to Fudge Tunnel to Tool.... well, you get my drift. I'm looking for a distortion/fuzz that will work with any era of heavier rock. It must sound good thru passive and active basses. What do you suggest? I've heard good things about a few... leading the way is the Fulltone Bassdrive, followed by: Prescription Depth Charge Frantone Lo-Tone E.H. Big Muff Pi E.H. English Muff'n Z Vex Wooley Mammoth(although not with active) What are your thoughts, experiences, etc.? What would you do? Thanks.
