Q-Tron

The Q-Tron is the definitive envelope filter for modern players. Designed by Mike Beigel (creator of the Mu-Tron III), it captures the funky, vocal-like quack of the 70s with improved stability.

History & Legacy

Released in the mid-90s, the Q-Tron resurrected the classic opto-coupler filter sound.
