When I got my bass last month I picked up one of those 8 dollar clip on piezo pickups designed to plug into a tuner. Figured it might be handy. The other day I plugged it into my rig, just for s***'s and giggles. Went through my eq with a decidely drastic cut on the mids, into some light compression then through the "DI" on my studio pre.....
You know, after playing around with placement on the bridge, I got some sounds out of it that didn't make me want to run screaming. Placement - and how firmly against the bridge the crystal is being held - are obviously a big part of the sound.
I know you're all laughing, but I'm totally rehearsing with this set up while I shop around for a real pickup. I mean, 8 bucks for crying out loud!
Okay seriously though - reading the few "which pickup should I get-" threads, including mine, the constant seems to be that one pickup does not work for all basses - soooooooo - when's someone gonna come out with a DB pickup that can be placed anywhere on the bridge? Not being restricted to installing in one spot might make a pu really versatile.

8 BUCKS!!
