Dug out my DEM today. Most here, probably know how this pedal sounds already. For those who don’t, I made up a simple demo.

I figured some open chords to demonstrate the slow “whooshing” sound. Around 1:10, I kick on a Double Muff(double mode). You can get an idea of how hitting it with an dist/fuzz/od will affect it.
Settings(o’clocks) are Color = 9:30 Range = 5 Rate = 8:30

At around 3:50, I set it for a Leslie/Univibe-like setting. It isn’t perfect, but comes close and will do in a pinch. The OD, at the end, is a Double Muff(single mode).
Color = 11 Range = 11 Rate = 2:30

I used a Gibson LP w/ AlNiCo II’s and a Fender Champion 600. I miked it with a Shure SM57. I added some compression in Pro Tools.

Any questions just ask.

Thanks,
Ming
