This preamp is essentially new. I had it installed for approximately 2 weeks in a Vintage MIJ Fender. It sounded great but I decided to go back to the original Fender set up in order to keep the bass "Vintage". With the Audere Knobs I paid $159 this preamp.
The description from the Audere website is below.
Controls:
Volume
Pickup Balance with center detent
High / Low Mid Tone Controls with center detents
Treble / Bass Tone Controls with center detents
Output Jack on wires
Features:
True organic sound with superb string touch response.
Active Balance or Volume / Volume pickup mixing systems expand the useful pickup mixing combinations.
Active Tone controls have a flat frequency response in the center detents and support both subtle and more extreme sculpting.
Supports all types of active and passive pickups.
Easy to install:
Small in size to fit in most control cavities.
Pots and switches are on wires and can be positioned as needed to fit your bass body.
Battery box is not required but can be used if present.
Runs on either 9 or 18 volts and sounds the same in almost all cases.
