Hey folks, I had these up for sale a few weeks back with no takers and didn't want to deal with eBay, so I'm relisting them at a new, ridiculously low price!
The volume pots are already wired to the preamp, so you'll just need to solder in the pickups, add the knobs of your choice, and you'll be good to go.
By the way, the BT preamp is the same one used by Dingwall in their acclaimed Combustion basses
$80 $70 $50 shipped for the entire package
