This is a handmade, analog-like digital delay pedal using the PT2399 IC, which is used in digital delays. It has the minimum necessary four knobs: MIX/TIME/FEEDBACK/TONE, allowing for a wide range of sounds, from short delays like chorus to fantastical long delays. The TONE knob acts like a filter, and when fully open, it produces a rather aggressive sound. It can also produce oscillation, which is not possible with digital delays. The unique sensation of the sound changing as you turn the knobs is addictive. This pedal is made and tested after receiving your order. *It runs only on a DC9V adapter. I make various other pedals as well, so please check out my profile. I have a demo video on YouTube. I can't post a link, but please search for ksstomp to find it.
