I've been going through a personal crisis with an EB/MM Stingray 5. In the past month and a half, the neck has developed terrible backbow that made the bass completely unplayable. In the early stages of my dilemna, I took the fret buzz in stride. First raising the saddles, and resetting the intonation. It was a short term fix that only lasted a few days. With the problem getting worse, I loosened the truss rod and hoped for the best. Once again this did nothing and the bass deteriorated into a monster with the strings making absolutely no noise when fretted anywhere between the 3rd and 12th frets. Figuring that I had done all I could, I took the bass into my local repair shop, and asked for help. They once again loosened the truss rod to the point where it is completely loose, and told me that the wood had warped in the opposite direction of the fingerboard. Ultimately making the bass useless, and telling me that the problem might fix itself as the humidity and temperature changed. At this point I contacted EB/MM and asked them for advice/solutions, etc. and was informed that the bass had to come in, and if it needed a new neck (which sounds like it might), it would be rather pricey. Seeing as my financial situation is not great, this isn't really an option. Finally last night, in a last ditch effort to make the instrument functional, I shimmed the neck (It was either this or in anger and disgust smash it against the wall). This helped, but didn't elminate the buzz. At this point, the entire A string buzzes, and certain notes on the D and G strings sound terrible. The action is as high as it will go and the truss rod is as loose as possible. So, in conclusion, anyone that has an idea on how to fix my poor ailing 5er please help. Thanks in advance for any advice.
