Designed by Mike Beigel, inventor of the legendary Mu-Tron III envelope filter. The classic envelope follower with FX loop. Place your favorite effects between the preamp and filter section without changing the envelope drive. Be creative with the effects you plug into the FX loop and invent totally new sounds. Ratify your Mojo! Electro-Harmonix Q-Tron+ Envelope Filter Pedal Specifications:
Drive (Up/Down)
selects direction of filter sweep : upwards or downwards.
Norm/Boost
Normal mode allows setting the Gain control without changing the output volume.
Peak (Q on the Mini Q-Tron)
Determines frequency peak of filter. Makes more "effected sound" when turned up more.

Emphasizes vowel like sounds in low position, overtones in high position.
Mode (LP/BP/HP/Mix)
Select the filter used by the effect: Lowpass, Bandpass, Highpass or a mix of Bandpass with dry unprocessed sound.
Response (Slow/Fast)
Selects either a slow, smooth, vowel-like attack or the fast, snappy response of the original Q-Tron.
