Mica, that's what my bass had. The previous owner had replaced the original harness with a homemade bass-treble-volume preamp and on/off switch that I swapped out for Activator guts picked up at a yard sale before I bought the bass.
Hey, I was a college student.
There's no mistaking the greenish tinge of that bridge pup; the leads had been clipped before I bought it. I'm sure you don't remember this, but you and I corresponded about six years ago about fixing the issues that harness had.
Drat and double-drat, the foolishness of youth! Let my suffering, well, vague discomfort, be a lesson to all!
