Envelope-controlled filter

The Electro-Harmonix Q-Tron+ is an envelope-controlled filter whose swept cutoff tracks the dynamics of the player's attack for organic auto-wah and funk-filter sounds. It offers low-pass, band-pass, and high-pass modes with Drive and Q controls, plus an effects loop and response options for expressive filter sweeps.

    Electro-Harmonix (EHX) is an American maker of effects pedals for electric guitar and bass, founded by Mike Matthews in 1968 in New York City. An early pioneer of affordable stompbox design, the company is best known for the Big Muff Pi fuzz, along with influential models such as the Small Stone phaser, Memory Man delay, and Electric Mistress flanger. After closing in 1984, the brand was revived in the 1990s and continues to design and build a broad pedal range in New York.
