There are three (that I know of) docks made by me that have tuner connectors dangling out the backside. Easy enough to hook up: just need the tuner Molex connector, and the extra gold pins for the docking connect, and some hookup wire and stuff.

The Parts List thread has part numbers for all of this. I found the Molex connectors at my local electronics shop, but some people just cut up the "tuner extension cable" that came with their (original Empeg) tuners.

Cheers
