Electro Harmonix Q-Tron Plus Envelope Filter

Versatile little box, I use it mostly to add a little funk 70s vibe to soundtracks on Guitar and Synth, yet with the options of LP/BP/HP etc means it doesn't always end up sounding like a cheesy cop series!

Pros: Quite easy to tune in the envelope follower to different sound source volume ranges, something thats always tricky on some pedals.
Makes a synth without a filter like the DX100 sound instantly funky, no need for a talk box!

Cons: Would be handy to have a cv or pedal input to experiment with external control, maybe something I'll hack onto it at a later date.
