Improve your Groove!

The Electro-Harmonix Q-Tron - the phattest, funkiest envelope filter ever made! Features like switchable Boost and Filter Mix mode allow for an unlimited supply of all-new auto-wah effects that drip with attitude. Increased frequency response and improved signal-to-noise ratio make the Q-Tron perfect for use with any instrument.

Bootsy Collins and George Clinton already have theirs. How about you?

Designed by Mike Beigel, inventor of the legendary  envelope filter.

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 - Determines frequency peak of filter. Makes more "effected sound" when turned up more.

Gain - Functions as both a volume control and a filter sensitivity control in boost mode. In normal mode it acts only as a filter sensitivity control, unlike the Mutron-III which also changes the unit's output volume.

Range (Hi/Lo) - 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.

Comes with Power Supply, New Footswitch
