The channel one rotary encoder on my Yamaha DM1k snapped off. I need someone who can get the part, open it up and swap out the encoders. I priced it out and I don't think it is going to be cost effective to ship this for the repair so someone local to Boston would be in order. If you can do this please shoot me an email ([email protected]) and let me know what sort of turn around I could expect and roughly what you think this would cost me.
