Hey guys, its been a while. Well recently I've taken up an astounding interest in modifying my bass guitar (crappy Ibanez GSR 200). So far I'm ebaying some new pickups and I've already installed a kill switch (kill switch on a bass, AWESOME, and completely and utterly useless I know

). However, I'm itching for some more modifications I could do but can't seem to come up with any new techniques/ideas. Any suggestions?
EDIT:
Some possible ideas:
New bridge (tremolo maybe?)
A bit on the extreme but hey, KP-Mini KAOSS Pad embedded in the bass?
