Rebote Delay 2.5

This is interesting digital delay project from TonePad which uses PT2399 delay chip. PT2399 was intender for delay times up to 400ms, but here it can go up to 580ms (I measured 625ms maximum delay time on my build) causing noticeable distortion at longer delay times with level turned up. It could be a problem if you need clean delays at longer times, but otherwise it’s not a big deal. At first it didn’t work, like in many other cases I saw on forums it just didn’t delay, dry signal was coming out with pedal turned on. After messing around with it and with great assistance from DIY Stompboxes Forum I found one solder bridge that caused problems. Everything in my build is stock like suggested in article, caps are mostly WIMA Foil, but there are few Siemens and few poly caps from local store, resistors are metal film with 1% tolerance.

    Hi, there. This is not the first time I check your web for very usefull information, but the first time I take the time in reading everything from your effects page.
    One thing ’bout the Rebote Delay. It is an intended effort to recreate an analogue tape machine. That would result in the distorted and fuzzy sounds in the repetitions after long delay configurations. There are several mods for this circu it in particular, to get “eternal” delay, but, offcourse, it would result in a painfully annoying noise, after a few seconds of stop playing.
    Sorry for my english, greetings from Argentina.
