Electro-Harmonix releases Q-Tron Envelope Controlled Filter

March 11, 1998 -- In 1972, Musitronics Inc. introduced the world's first self-contained envelope filter, the Mutron III. Its unique "automatic wah" sound quickly became a staple among the funk and rock genres and can be heard on recordings by Stevie Wonder, Larry Graham, Bootsy Collins, and countless others. The III finally went out of production in 1979, and original units fetch outrageous sums on the vintage market.

Today Electro-Harmonix proudly introduces the Q-Tron envelope controlled filter. Designed by Mike Biegel (the engineer who created the Mutron III), the Q-Tron is the first new product from EH since 1983. Using the same opto-electronic circuit as the III, the Q-Tron offers up the same liquid, vowel-like wah wah sounds, but with an increased frequency response and improved signal-to-noise ration. Several new features set the Q-Tron apart from any other envelope filter on the market.

Housed in the standard Electro-Harmonix brushed-steel chassis, the Q-Tron features the following:

Switchable Up/Down Filter Drive switch
Variable Filter Peak control
Hi/Lo Range control
Selectable LP, BP, HP and Mix (BP and Dry combined) Filters
Variable Gain control and Overload indicator
Switchable Boost feature (disengages preamp section)
Effect and Direct Outputs
AC operation with LED Power indicator

The Q-Tron is assembled in the USA and comes packaged in a sturdy wooden box with the unit's face screened on the slide-off top. The suggested list price of the Q-Tron is $249.
