chef said it ... Audere & MFD's ..mmmmmm Still sounds like a G&L but with a bunch more flexibility.
The bass that sold me on Audere was Dave Meadow's personal L2000 with NO TONE CONTROLS ! His is wired up Master Vol, Neck Vol, Bridge Vol, z-mode and coil selector's ... I spent the day after I demoed it trying to buy it ...
I am not a fan of the active L2K tones though - how often does one actually need a 10 db boost on a switch ? or treble on top of that ? Nope - my fav L series tones are the passive ones. The Audere let's that same character ring through and if you really want that gnarly treble thing ... use the EQ ...
My pre was re-worked by Dave as I originally ordered it with no tone controls - then decided I needed EQ later. It is essentially a stock 3ZB Vol, Blend with stacked mid, stacked Bass & Treble.
Installation isn't all that bad but you do need to solder. Happily the G&L pre somes out intact. 1 piece so with a diagram of where the pickup wires went - it can be easily reinstalled.
You also need to get two On-On-On DPST switches (Dave may be able to supply them, I got mine from Butch at Bayou Cables,
Stew Mac has them as well.)
On the pickup itself, there is a green wire that grounds the pickup 'chassis'. It connects to ground in the control cavity. That one get's unsoldered from the pickup chassis (booster magnet I think) and you have to solder in a jumper to connect the two pieces together.
Then you;re on to wiring the switch which follows the Dimarzio humbucker wiring scheme. There is a diagram for single, series, parallel out on the web. Should anyone decide to give ita shot, I'll hook you up with that if you need it.
