Hi Steve and Michael. You may have been borodged with this question before. What distortion or metal pedals work really well with a 100% passive fender jazz bass? I've looked in the search for key words but I have come up empty. The Big Muff I have is the new new york usa reissue, it worked great with my ibanez btb but sucks with my new bass (that sounds great clean, but bad with the pedal). I do not like the bass versions of the distortions, I prefer guitar fx for the bass. Would an envelope filter work along with the big muff so that I don't get the low high split with everything fading in and out? That pedal really just sounds like cr@p. I know you deal with much more important stuff but I would appreciate it if you could solve my problem, you may have solved it before.
