I decided the other night that I wanted to bring my 1977 Kramer aluminum P bass out of retirement. It had been put there because the neck is a little funky, the sound is very bright no matter the strings, and mostly because I finished building my fretless J clone. But I was looking for something a little different, so I whipped out the old guy and started fiddling around. I "solved" the neck issues by raising the action until it didn't buzz anymore, and I fixed the twang by going to Radio Shack and buying a few capacitors. First I tried replacing the old .33mfd with a .4j, not quite as much change as I wanted. Then I tried a .1mfd, which was pretty nice but still not where I wanted it to be as far as range of possible tones. So then I whipped out the big bad 1.0mfd cap that I bought just because it was big and cool, soldered it in, and WHAM! I've got tonal range like nobodies business (at least in passive basses). I can go anywhere from a tweaked out, way too much high end sound down to a very thumpy, woody upright sound. It was such an amazing change that I couldn't help but recommend it to anyone out there who needs a change. That and because I wanted to see what the biggest single tone cap anyone else had installed and liked was. Peace out, yo.
