This is one of the most exciting things I’ve ever built! It’s an analog sounding delay with modulation (chorus, vibrato..). It also has switchable delay “trails” so when you switch the pedal off the delayed notes fade away slowly instead of cutting out instantly. “Warp”-switch sets feedback to maximum so it can create crazy self-oscillating sounds almost instantly which is really cool :) Playing hasn’t been this fun in years!

Because it’s quite a complicated build I got a ready made circuit board from Music PCB and I highly recommend it, great quality!
