ACG EQ-02 Filter Preamp (3 knob)
Drops in to a Fender Jazz. No Soldering required. Check out the thread below, emjazz does a great job of explaining how this thing works.
ACG onboard preamp (ACG/John East design)
As far as my thoughts on it. The preamp kills. It has an extreme number of usable tones. I never knew what people meant when they would say that a preamp was "musical". I do now. This preamp is exactly that. Very smooth and ... well.. musical.
It is a very well made product. No scratches, and is in brand new condition. I am selling it, because I sold the bass it was in and the guy didn't want to fork over the extra $$ for it.. So now, I have a preamp needing a new bass.
$290 shipped CONUS.
