Hi, I'm the inventor of Mu-Tron III and most of the other original
Musitronics. Looking at the reviews on the Mu-Tron III (and I suppose
the other Mu-Tron products as well, I notice that people do not know
where to find repair services for these products.
There is an excellent repair service for ORIGINAL Mu-Tron products from
Musitronics. Richard Lingenberg of LINGENBERG SOUND studied and worked
with me on the repair and recalibration, and also custom modifications
of these products. I highly recommend him. Buyers of vintage Mu-Tron
products need not worry about repair service for these fine vintage
Thanks and best wishes.
