High NoonStereo PT2399 Ping Pong Delay

From the vendor

The High Noon ping pong delay was the subject of the “How to Design a Guitar Pedal” video series that I did (find it here). It's a pretty straightforward design, but it represents a great project for getting into stereo effects. It can be set up to take either stereo or mono in and can be either stereo or mono out. In a mono in/mono out configuration it just acts like a dual tap delay. With stereo out, it functions like you would expect a ping pong delay to: the signal gets delayed out one side, then the other, back to the first, etc.

Additional features of the High Noon include a “Sync” switch that allows the second delay line to have its time and mix level synchronized with the first delay line or to be independent. There is also a “Mod” switch which introduces some subtle modulation into the first delay stage, which gets propagated to the second stage.
