Benson Delay

[jwyles90]

Have no idea what it looks like on the inside/circuit wise, but apparently it’s a pt2399 based delay. I had a chance to play one at a pedal expo a while back and it sounded pretty killer.

Are smd 2399s more reliable than the through holes?

I read someone saying that (Schutone?). I would expect so, the through-hole fab machinery must be 20+ years old now.

I'm not sure if I have ever said that, and I have absolutely no data to back them up being more reliable.... but I do use the SMD ones a lot, and haven't found a bad or super noisy one. So take that for what its worth.

That sentiment was what my memory was telling me. I could have also just made it up and attributed blame to you Getting senile in my old age..

Ha! It works both ways, I totally could have said it and not remembered

I've fixed at least 3 of my "broken" delay pedals now by simply swapping the PT2399

PT2399 chips are not terribly consistent in my experience. Before you go too far down the rabbit hole, maybe pop a different one in and see if that helps?

This ^^^. Try several chips and ideally from different sources. I usually buy at least 2X what I need so now I have a good stash to pick the least noisy ones from.

I think I have a few extras, so I will try that. The "sounds like trash" I spoke of included getting oscillations with no input. My power strip appears to have been an issue there. Now I get delay even when "bypassed". I will try to record a demo of what I have tonight. Gotta finish with my 9 year old's birthday festivities.

So who's made one of the "Noise Ensemble" pedals and stuffed their bad PT2399 in it? Did it work? Did it sound like it should?

 

[cwsquared]

What works on my Echo Royal does sound exactly like the demo from BYOC. So, I think my 2399s are OK. I still get "wet signal" when bypassed, delay length isn't affected by the far right delay time pot, and it self-oscillates really easily (I need to mess with the internal trimpot). But I think with some troubleshooting, I can get it right, just not that soon.

For the money, I think other options would be better though. I think this, like the Crown Jewel and Super 8, requires a BYOC specific MCU, so we will never just get a PCB-only option.

Was someone able to get an schematic from this pedal?

Adding to the secondary topic, has enyone tried Tayda's smd CD2399 ICs? Those are dirt cheap

Even the original PTC chips are quite cheap (try LCSC). I wouldn't take a chance with a clone by some even more obscure fab. I tried two non-PTC "PT2399" chips, one worked fine, the other was unusable. At 3 Volts, I mean
