Pas besoin d'être un puriste pour le dire (c'est d'ailleurs mentionné sur le site) la techno utilisée est à base PT2399 qui est un chip numérique. Cette pédale est basée sur un projet très connu le rebote delay de chez Tonepad. c'est un delay numérique créé pour se rapproché le plus possible du caractère des analo avec les oscillations et tout. Un autre projet dérivé est le PT80 de chez General Guitar Gadget.

Why digital? Isn't Analog better for a solid-state solution?
Well, in many ways, the delay medium is less critical and it could be an oil-drum, tape, metal-thread, analog BBD or digital, but the final sound is always set by the limitations of the delay medium and the peripheral circuitry needed to make either work. We chose Digital construction to make it compact, stable, with reasonable delay time and virtually service free, where the limitations of the circuit would be less critical. As an outcome, you can set the peripheral circuitry with desired bandwidth and distortion levels with less consideration on the exact limits of the delay medium, while of course always pushing the limits, as with anything musical.
A similar circuit in analog form would be excessively more expensive to make. For the same performance, it would require three to four of the best BBD chips now only available as vintage parts and the size of the pedal would have to be about three times the current size.
un circuit assez ressemblant a été publié et partiellement validé par BJF lui même.
