Haz Lab Preamp (Please Read) - This is an old Haz Labs pre out of a fodera, don't know what bass, never owned the instrument. This preamp does need one of the pots replaced, two of the lugs snapped off of the main assembly, should be an easy enough fix for someone good with electronics - Price is $115. Sadowsky, Had this in a bass that used a different input jack which is wire the wires need to be re soldered, still plenty of lead left so should be an easy process. 200 OBO for that.
