Its twin soapbar single coil pickups, tone pot for each pup, + single blend + single volume, + active / passive mini switch.
Neck pickup is fine, tone working, but the bridge pickup tone is bizarre. When the tone is full up, volume on full , it should be very toppy, but its the opposite. Volume is fine. When rolling off the tone, almost all volume disappears and tone is extremely thin and trebly. The loss of volume is huge, though still audible.
Hard to diagnose for anyone i'm sure, but is this the tone pot's fault, or bridge pup going down ?
