Rewiring Mike Watt Bass

I picked up a bass guitar originally owned by Mike Watt - custom built for Mike in 2001. Even has his name on there! Anyway, the bass is way goofy with the two passive pickups -A Lane Poor P-Bass pickup (neck position) and a Kent Armstrong Music Man Style pickup in the bridge position (Mike Watt swapped pickups when he owned this bass). There are two flip-style switches on this bass: you mute either pickup and use just one of them or you can combine them.

The issue with this setup - it's all passive, LP pickup is really quiet and the Kent Armstrong is crazy strong in the signal level. It's a pain in the butt to switch pickups live with such a huge volume change. The combined volume of the two pickups is just slightly louder than the LP pickup by itself.

I want to increase my signal level and get the pickups to the same output level or at least closer. Soloed or combined, I need to have the levels really close to one another. Is that possible?

Thinking of adding a Glockenklang pre-amp, but what else should I do to achieve my setup ideas? I am not a big fan of passive tone knobs, and extra EQ knobs (besides a bass knob) are not helpful to me. I am trying to NOT piss off the sound guy!

2001 Thelacaster 4 string, Check it out!

 

Mahogany Back combined with Ash and an Ash top. It sounds like a P-bass, but tone is much thicker and growlier. It's a unique sound and I know I like it way more than any other P-bass I have tried....

Maple Bolt-on Neck, Ebony Fretboard, 24 frets, 35" scale - no string flop at all! Stiffer feel overall on the strings, but that's how I like it.

 

Just bumping my thread...... does anyone have any input on this topic? Is it just not possible to do such thing?

 

I have heard that a blend knob affects the overall tone of a pickup and that a Dual volume control setup does not. Is there any truth to that?

I don't know enough about pickups, but will a blend knob bring the signal level down of the Kent Armstrong pickup without altering the tone?

Is the key here to get the Lane Poor pickup to the same level of the Kent Armstrong? Or vice versa? Should I forgo the switches on the bass? I really just want to use the pickups separately or together.

 

I bought it from BassNW last week.
