Good one!!! It's An 89 5-string. I mostly play the bridge pu so im not messing with the selector switch much , but the knob falls off every now and then and i never can find the .050 allen key when i need it. It(the bass) used to reside in Jersey w/ Danno, and I seem to recall him saying it got refurbished @ the mothership. So Who knows how old the pots are.....
