The EHX Analogizer (http://www.ehx.com/products/analogizer) is a guitar pedal that apparently consists of a ultra-short delay with some gain stage. It's supposed to "fatten" and somehow "spread" the sound to make it appear more "analog" (thus: dirty). I wanted to quickly test the effect myself.

I guess with some additional care of the distortion stage and maybe some very little modulation (stereo!) it could be way improved. I obviously don't really know what's going on in the inside of the original pedal...

nice work. ah, the guitar pedal industry, where a feedforward comb filter is marketed as an "analogizer" and costs $72...
