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.

1998 EHX Q-Tron+ |
2000 EHX Mini Q-Tron |
Since then EHX has released several other units with roots tied to Mu-Tron. In 1998 the Q-Tron+ was released with technologies similar to the BSL below. In 2000 a Mini Q-Tron was developed similar to that of the original Mu-Tron.

Lastly in 2004 EHX released the highly anticipated studio quality Bi-Filter with roots deeply connected to that of the 1979 BSL Envelope Controlled Filter.
