Help!! My Cort Curbow bass has developed a strange electronics problem. Its output has weakened so much I have to crank up the amps to their limit. Even a passive Epiphone bass has a hotter output.
My Curbow has a passive MightyMite humbucker pickup, soap-bar style; and an active circuit that has volume, Bass, Mid, Treble & a "Slap switch" that engages a different EQ setting. I think it's a Bartolini MK1 circuit.
The instrument's tone is the same, the EQ & slap switch works fine, there's no broken wires, the volume pot works fine and the 9-volt battery is new. What do you think it's happening? Thank you!
