Original "large box" Electro-Harmonix Q-Tron Envelope Filter pedal in very good condition and perfect working order, for sale with original wooden box.
This pedal is the envelope filter based on the Mu-tron III design, and it sounds very similar (certainly better than the terrible Haz Labs reissue Mu-tron). Mike Biegel, inventor of the Mu-tron recommends this pedal as the nearest equivalent to an original Mu-tron. A whole world of funky filtering can be yours and very much in that great 70s analogue filter territory. This is a really cool auto-wah type effect that really responds to the dynamics of your playing: works well with guitar, bass, rhodes, wurli, even synths if you get the input level/sensitivity right - particularly good on guitar with some fuzz beforehand...

Condition is very good - the metal case has some scratches but overall it presents very well - see the detailed photos.

As well as the wooden case, it comes with a 240v PSU if required (it has a Euro plug on it but there's also a UK adaptor if you need it).
