One of the issues with most PT2399 delays, which this is, is that the PT2399 delay chip leaves a lot of digital artifacts or distortion in the audio signal. This is very noticeable on a lot of delays if you turn the Mix up with the repeats. It almost sounds like a "bit rate" noise. This pedal uses a charge pump or pre-amp and with proper biasing and delay level the pedal does not seem to have any artifacts or distortion in the repeats. It's really a great design. Hats off to Jon Patton (midwayfair) on this circuit.
The pedal operates with the standard controls: Delay (this controls the length in between repeats), Mix (this controls the over all volume of the repeated signal), and Repeats (this controls how many repeats you would like for the "note" played). As I said above the overall level of the delay is controlled with an on board trim pot as are the tone and bias as well. The art I used was adapted (like that fancy word I used there) from an actual Hamlet Play flyer. The enclosure was a scratch and dent from Pedal Parts Plus. It was already powder coated the green sparkle color. Her are some pictures of the build. I will post a video later.
