If you want the original sound and circuitry of the Mu-Tron III, please buy either a used vintage original Mu-Tron III (and NOT the so-called "Mu-Tron III plus" please). Better yet, buy my new MU-FX TRU-TRON 3X which has new features and better specs and retains all of the Mu-Tron III mojo.

A brief Mu-Tron history lesson..



Mu-Tron III

The Mu-Tron III by Musitronics Corp. first came out in 1972. Since 1996 the Q-Tron developed by Electro Harmonix has been the successor to the legacy which is the Mu-Tron. In early 1995 Mike Beigel was commissioned by Mike Mathews (owner of EHX) to reinvent the sound of Mu-Tron, today EHX still sells that sound as the Q-Tron.
