Its been a while, 2011 actually when my Fender Jazz 24 Korean made bass preamp died. At the time I spent a lot of time researching fixes for this, and got a lot of advice. Back then I purchased a SD 2 band EQ preamp as the solution. The repair never happened as I moved onto other bass guitars, so not im going to finish the repair and close the book on this. I saw a few posts from 2013 about this bass and the DD BEQ-3 preamp, so was hoping there may be new info available.
