I'm selling a K&K bass master pro pickup. I putting for sale here before it goes on ebay. This is a great sounding pickup system.Includes the Bass Max and Double Big Twin transducer sets wired to a stereo endpin jack, a stereo (TRS) cable, and the K&K two channel preamplifier with volume, overall gain, tone controls for each channel, and mixed output. It also comes with several strips of pickup tape. I will let this go for $210 shipped.
