O.k., I understand that the way I use my fingers has a lot to do with my sound. But you just can't tell me that the amp has nothing to do with sound. So, what head is essentially known for that jazzy wah sound but can still get that growl out of the low end. What I'm looking for is the Radiohead low end and the Jaco jazz on the highs. My problem of late has been that I can't get my highs to cut through. And I don't want them to be all sharp pingy. So I'm lookin for that Jaco high end. I have a P-bass with a double jazz so I got that covered. Also, is there an e.q. trick I could use to give my high end some bass and presence? Thank you.
