I have a rear-routed Warmoth Jazz bass. It is currently using SD Ultra Jazz pickups and an Audere pre-amp. In total, there are five holes in the top of the bass for the Audere controls. I'm really more of a passive guy, and want to pull that pre-amp out. How would you re-wire it and still use all of the control holes? I was thinking LP style- 2 vol, 2 tone, three-way switch. I'd like to keep it as simple as possible.
