PT2399: What sounds good/bad?

[AntKnee]

I haven't built many delays, but I've seen multiple mentions of some sounding better than others. I've been lucky I guess, that none have sounded "bad", or maybe I just don't know what a bad chip sounds like. So, my question is... What does a bad chip sound like? Conversely, what does a good chip sound like? What sound do you listen for?

I've used dozens of these chips, and I can verify that some sound good, and some bad. Really what I mean when I say that is that, some of them have cleaner long delay repeats. Bad ones distort, have noise, get muddy (and not in the good way), and some even never get long in terms of their delay times.

I believe it all has to do with tolerances and manufacturing. Like with any chip, if you get multiple manufacturers with tolerances, there will be ones that work to spec, and ones that don't.

Turn it right up to here it. My camera wasn't great at picking it up. But it's way louder in person. First is a good one, second is a bad one. It's the first batch of bad one's we ever got from Tayda, and they were all bad. Essentially we only get pots from them now.
