Q: Do Bartolini Preamps work with Passive Pickups?

A: Yes, that is what they were designed for.

Q: What is a prewired harness?

A: Prewired harnesses have the potentiometers and switches (if applicable) wired to the preamp modules as well as to a battery terminal and a jack. In most cases, the only connections that will need to be made are connecting the pickup wires to the pots and ground.

Q: Do the controls have to be in the locations shown in the layout diagrams?

A: No, Bartolini has left a bit of slack in the wires to allow for some flexibility in the layout of the controls.

Preamps with a push/pull mid selector allow for changing between 250 and 800 Hz. Preamps with a switch allow for changing between 250, 500 and 800 Hz.
