Something glitchy

Quite fancy building a glitchy delay is there a schematic for something of that ilk?

look at the PT2399 datasheet delay, breadboard their basic configurations and noodle away (throw some caps, pots and diodes in weird places if you're lost for inspiration)

check out Clari(not) or Noise Ensemble. good ideas for experimentation

+1 the Noise Ensemble sprung to mind immediately and the clari-not + although not really glitchy but very cool the deluxe pitch pirate out of which you can get some weirdness I love it around 2.00 and 3.29 in the video

I've tried a square wave LFO on a PT2399 and it was weird/fun

Look up the MWFX Judder. Don't know if there is a layout/schematic, but there are "clone" videos on youtube.

This is probably for Slacker and Lars, who commented on a similar project I had done, and might be useful to others to. My thread is at topic http://www.diystompboxes.com/smfforum/index.php?topic=113467.0. To make it easier, I'll repost a link to the circuit I ended up building.

Its a similar idea but much simpler design (no midi).  I basically hacked a SEIKO Quartz Metronome, model SQM-300, to include a pulse stretcher and a tiny OMRON relay. Maybe 6 parts total, plus a small output jack. I've wired my JAMMAN looper similarly, so now I can simply dial in the tempo I want on the metronome, and the JAMMAN looper will follow it. Since it worked so well, I may go for a dual contact relay next, so i can "slave" more devices, ideally bot a drum machine and the looper. As is, I was lucky enough to be able to kludge-fit all the parts right into the existing SEIKO metranome. I may cut a PC board and make them if others are interested, but I'm sure a lot of people on this forum could wing it as I did.

Anyway, it works pretty well. I did have a hicup before I put in the pulse stretcher. Even though the relay was fast enough for the 12mS pulse the metronome generated, the JAMMAN looper didn't respond well. Once I stretched the pulse beyond any reasonable "debounce" timer, the looper followed it perfectly.

if you don't want to do programming, the pt2399 is def your best bet! if you're comfortable at al lwith breadboarding and experimenting, I'd get a few, and feed various noise sources, lfos, envelope generators into the chip's delay time (via vactrol or transistor). gotta get creative, there's no 'traditiona;' delay schematic that will get your glitchy delay, though it will certainly be a good start

You could try a tremolo with a very fast setting.
Take a look at the Trolling fun thread I just started and just use the op amp tremolo and the LFO. It gets pretty choppy on fast setting.

Just a thought

Forget that ^

Try Freppos Black Current Tremolo.
