You might have seen my previous posts about my KSD Proto J. Unfortunately there was no happy ending.After all the tweaking I did with it, I adjusted the trussrod one too many times.It had a very poor fit at the nut to begin with I should have returned it before I started messing with it.It never came with a wrench and I unsuccessfully tried to get the correct size from the dealer and also the Importer Brooklyn Gear. It seemed to be neither metric nor American,So I went with the closest size and it worked for a while. Now the inside of the allen screw is rounded off and no more adjusting is possible. I tried to get a new nut from Brooklyn Gear... multiple e-mails and messages...no response. Bass Specialties in Philadelphia, where I bought the bass was absolutely no help either.Ken Smith does not even want to have anything to do with the product.He totally blew me off earlier when I had a question about the preamp and pickup locations. Fortunately the bass is set up well right now and I don't want to mess with it and a luthier in my town also did not want to touch it. I can't sell it as it is so I'll keep it for bar gigs where i would not want to take my more valuable basses. People notice the proto J because it looks like a Sadowsky or a Lull but there were so many things I had to do to the bass before it was nice.In hindsight, it was not worth it.I spent a lot of money and now I have a bass that can't be repaired. So if you are thinking about getting a Proto J ....don't!
