A quite interesting PT2399 delay with a ringmod circuit in the wet path for dirty and robotic delay repeats. Schematic is avaiable HERE.

Just built this one up. It is pretty awesome. Dirty, noisy, f'd up take on a PT2399 delay circuit. Couldn't find a demo vid for this particular version of the circuit but I'm going to say that mine 1) sounds like a lo-if delay with a ring mod in it (I used an LM567) and 2) you should tag it 'verified'
ReplyDeleteAlso - I had to add a booster to the input in order to get the dry signal up to unity gain. Don't know if that is something in the circuit design or just my build. Either way - you might want to tag this one with "Noise" since the glitch switch can act like a white noise generator depending on where the ring mod freq is set.

DeleteThanks for the report and for verifying it.If I find a schematic for the later revisions which possibly have an op amp stage up front I'll whip up a layout for it.

Delete10K pot for the frequency control will actually cancel the ring mod in the repeats if you turn it full clockwise. The original schematic has a 5K pot for that control. Do with that information what you will - I think that the 10K makes this a more versatile effect.
ReplyDeleteAny interest in doing the Shagpile? Schematic up on the website.

Definitely interested. Schematics is saved, I'll see if I can make something out of it...
DeleteThink it’s an early version but a great company! Big fan of the blog by the by!
