I'm curious because I'd like to build a pedal based on that chip, but wasn't sure how it sounds as a delay without being in an analog-style circuit.

ya the filters and such are the same value as the data sheet on this guy. i will try to make video on the weekend if you want to get a rough idea of the sound quality. it sounds pretty good as is.

basically the circuit i used is the data sheet but with different output setup so you can blend wet and dry. the rest is just a 555 to generate the LFO and an opamp + FET to implement a voltage controlled resistor. there are some switches to move around the treadle pot/change 555 waveform etc (no companding

Am I to assume it's sort of a boss-like clean delay? It outputs close to exactly what goes into it? Yeah?

Please say yes. That's what I'm hoping for.

ya its pretty clean as long as your not trying to get 1 second delay out of it. I dont want to say exactly where it starts getting grainy but maybe up to .5 seconds is pretty good. ITs always using all the delay memory so the shorter the delay the better the sound quality.

You can get these for ~ 1.00-2.00 now so i mean you dont have much to lose in trying it out. i will try to make a clip for you though like i said.
