I just picked this up and got it in the mail today. Found out it's not going to work for my bass body. I've got 3 holes for pots and this preamp needs 4 holes plus input jack. I have not tried to install it. Whatever previous owner sent me is what you will get. Same condition (pretty good condition actually) as the condition previous owner had. It will come with pots, washer, nuts, and input jack. I am looking to get $80 shipped.
