The bass is almost ready. A new pick guard need to be trimmed and installed, but I could not resist to try it.

The sound is good and noiseless, but after playing it a couple of time I want to replace some potentiometer and remove the capacitor selector.

The current diagram is:

All the potentiometers are 500K. The Volumes are Logarithmic and the Tone is linear.

New configuration will have 250K pots for the split pickups.

All the pots Linear and no capacitor selector.

Pickups:

Humbucker: DiMarzio (original from Yamaha ATT SPL, unknown)

Middle: DiMarzio (original from Yamaha ATT SPL, unknown)

Bridge: Wilkinson MWPB
