Hi - I have a 71 Jazz bass that just doesn't sound good. The only way I can describe it is it sounds very thin - I play through either a 71 Bassman 50 or an Ampeg B100R. When I play my other guitars (86 P Bass, 86 Kubicki ExFactor, new 4003) through these amps, they sound great. Very punchy and in the case of the P, woody. So I know my amps, while not the greatest, are not the problem. So here's my question: what's the best way to punch up the sound of the Jazz: new pickups, professional rewinding of the old pickups, or something else altogether, like a pre-amp? Ideally, I'd like the Jazz to have more of a P Bass or Joe Osborn sound (even though I play with my fingers exclusively, I'd love to get something that approaches a pick kind of sound). One last question: I'm a bit obsessive about keeping this guitar as original as possible. Does that make rewinding a better idea than new pickups, or once you make any change, does it not really matter which change you make? I love playing this guitar when it's not plugged in; it's just a dream to play. But I never play it out because it sounds so bad! Please help! Thanks in advance.
