Here's what I found out about your bass in the instrument file:
top: Flame Walnut
accent: Maple
body: Mahogany
neck: 7-piece Maple and Purpleheart
scale: 34" long
fingerboard: Ebony, 2.063 x 2.930 (custom)
inlays: Pearloid (plastic) ovals
pickups: AXY56, move neck pickup 1/2" closer to bridge
controls: volume, rotary pickup selector switch, filter, Q-switch, bass cut/flat/boost, treble cut/flat/boost, mono output
originally made for: Midwest Music
birthday: July 9, 1991
The fingerboard was a custom ordered width. There's no record of repair or modification, and the electronics may have a pan pot rather than a pickup selector switch. I'd very much like to see the inside of the cavity, but I can't open your latest group of images. Please save in .jpg format if possible, thanks!
