I covered last year the release of the Soundblox Pro Classic Distortion pedal, an innovative modeling unit which can reproduce the tone of many legendary overdrive and distortion pedals.
Source Audio did it again, this time turning its attention towards envelope filters. The Soundblox Guitar Envelope Filter does all the clean 70s funky tones you would expect from an envelope filter but it is capable of much more. I especially love the way it can fatten a distorted tone, much like a good phaser can. The filter “action” can be controlled “manually” using the Hot Hand ring. If you don’t know what I am talking about, I suggest you watch this video showing the Soundblox Guitar Envelope Filter in action:
Note that there is a bass version of the Soundblox Guitar Envelope Filter.
