Our new 4 control hole unwired preamp kit features our new surface mount circuit board. For J-style basses, the kit requires a side jack, so all 4 holes on the control plate can accept the potentiometers. The kit includes an extra volume pot so you have the flexibility to wire it as Volume-Pan or Volume Volume. This is the exact same circuit and controls that go into every Sadowsky bass. Does not work with active pickup basses. Professional installation recommended.
You're gonna love the way you sound. I guarantee it!
