Beigel Sound Lab
was formed in 1971 and provided product prototypes of musical products. The first prototypes of a unique synthesizer and "Timbre Generation" filter bank were produced for Guild musical instruments by Mike Beigel
and Isidor Straus. Then Mike Beigel
set up Beigel Sound Lab to finish the production engineering and final prototypes. Shortly afterwards, Guild's president Al Dronge was killed in an airplane crash and Guild dropped the synthesizer project. We then produced a prototype envelope controlled filter from some components of the original Guild synthesizer, then formed Musitronics Corp
and invented the Mu-Tron III
and other products. In 1978 Musitronics
was sold to ARP instruments and I re-started Beigel Sound Lab to provide musical product design services on a consulting basis.
A prominant musician had asked for a more sophisticated version of the Mu-Tron III
, so I designed the rackmount Beigel Sound Lab Envelope Controlled Filter and had about 50 manufactured in 1980. Many prominant musicians including Elliott Randall
, Marlo Henderson, Tim Bogert, Michael Iceberg, Jeff Baxtor, and Will Lee used them.
From 1996 to 2011 I worked with Mike Matthews of Electro Harmonix leading to the development of 9 products. However, we still service Beigel Sound Lab and Mu-Tron
vintage equipment, and have a few selected units for sale from our in-house collection
