Here's my homebrew/parts bass I made from a Jackson Kelly guitar, and a Mighty Mite P neck.
The neck and bridge pickup are NOS Gibson TB+ pickups, the middle was a Rio Grande Pitbull, but I have a Jackson pickup there now.
The hardware is all Hipshot, bridge is brass, and the tuners are Ultralites. The nut is nickle.
Controls are an on/off for each pickup, volume and tone, both pots are push/push, one being a coil cut for the Rio Grande or Jackson pickup, and the other is a "solo switch", hardwiring the bridge pickup to the output jack, bypassing all controls.
