For sale ZON on board preamp only $50 shipped

I have a used on board preamp from ZON; The only reason I removed it , is because I'm used to having a mid range control and this preamp only has bass and treble (with volume and blend of course)
Zon preamp was removed from a ZonLegacy elite from 1995 it's great!!! The ZON legacy Elite is the top of the line bass They offer. Everything ZON uses is of fantastic quality and this onboard preamp is no exemption! Get it at a very low price ; it works great (9 volts).
