Decided to sell this since I am going all passive and traditional these days:
ACG filter preamp, 2 pickups, 3 stacked knobs=treble stack, bass stack, and volume/blend, comes with chrome knobs, the pots' threaded portion is long enough to be used in rear routed control cavities.
New $300, $200 shipped from me!
the bad: bass stack is slightly scratchy, not bad but a whoosh sound can be heard when the knob is tweaked. Alan told me that replacement pots can be purchased from bestbassgear.com (his US retailer)
If you like Alembic/Wal type of preamps, this is for you!
Here is what it looks like, I can take pics if you want
new Warmoth build
