I have a 2011 JTV59 that I bought second-hand at the beginning of this year. The model knob wasn't working, so I got it cheap. I figured that, if I was lucky, it would be a simple matter of padding out the inside of the knob to raise it enough to work. Unfortunately, it turned out that it wasn't that simple. I left it for months and then finally decided to do something about it recently. I bought a couple of Belton BTDS20HPT encoders, dismantled the original PCB-encoder assembly and attached the new encoder. Hey presto! It works. At least, it works from Custom 1 to Chime, at which point it stays on Chime instead of moving to Semi and then goes back to Custom 1 again. I've reflashed it, but it's still doing the same thing. Does anyone have any idea what might be wrong? I'd like to see this guitar up and working properly. I already had a JTV69 and bought the 59 in the hope of being able to save it from the scrapheap, which I guess I have done in part, but it's frustrating that it doesn't want to play ball.
Thanks for reading and thanks in advance for any suggestions.
