For sale Preamps by Zon , Bartolini and Status Graphite

I have 3 used on board preamps that I removed from some of my basses; they sound and work great! The only reason I removed them is because I'm used to having a mid range control and these preamps only have bass and treble (with volume and blend of course)
Zon preamp was removed from a ZonLegacy elite from 1995 it's great!!!
Bartolini (NTBT) was removed from a 2002 Sukop bass.
Status preamp was removed from a status graphite series 1 bass from 1989 (jazz bass style with vol-vol and concentric bass and treble).
All of them are 9 volts
