A couple of years ago I bought a brand new Sadowsky MV4, and within a few weeks, I purchased one of the retrofit Vintage Tone Control (VTC) kits and had it installed by my local guitar shop.
What I have for sale are the pots and knobs they took out to install the VTC. I will be the first to admit that I pretty much know nothing about the electronics in a bass (sad, I know), but as I look at the Sadowsky website and their wiring diagrams, I think this is the pot for the treble boost and the pot for the bass boost. The bass boost pot has a push/pull stem, which I believe turned the preamp on and off. The knobs are also included.
This stuff was only installed in the bass for a couple of weeks, so everything is like new. You can have everything shown in the picture for $20 shipped to the lower 48. Let me know if there are any questions. Thanks!
