I ordered this for one of my basses ages ago from Mark at Bassdirect. It took several months to arrive, and I've been away an awful lot since. Consequently I only just managed to go over and collect it.
I no longer own the bass that it was ordered for though, and it won't fit into any other my current stable of basses. I want my Jaydee's to sound like Jaydee's and I don't want to have any more holes drilled in my Zon.
It's a four knob 18 volt preamp. It's currently set up as volume, bass/treble cut and boost, pickup balance, and low mid/high mid cut and boost.
Two of the knobs, bass/treble and low mid/high mid are stacked, but these could be changed quite easily, and in any combination to separate knobs, making it either a 5 knob version, or a 6 knob version.
The switch is for the Z mode thing.

It comes complete with black coloured knobs.
It cost £180, and is completely 'as new', it's never been fitted to any instrument.
I'd like £150 which includes next day special delivery postage.
