Seems very odd to me, there are a few pictures showing clearly a 100pf for C22. I have no idea :D

Thanks a lot! I totally understand you dont want to remove the cap to measure it. But since Analogman has painted some resistors in the past (see the fsb forums), i wonder if they would use fake capacitors... just to play with us geeks :D (like the H he writes on the chip and output capacitor)

On the freestompboxes thread, someone mentioned another odd value for C22 on the yellow side (a 505 marked capacitor, see here: https://www.freestompboxes.org/viewtopic.php?f=7&t=382&start=360) I would think that 750pf is a bit much in that place, but maybe I'm wrong. I'd be very curious to know...

The best way to know for sure would be to measure the cap outside of the circuit... if you feel like its something you’re willing to do, that’d be great!

Thanks for your work! Yes it was confirmed on the freestompboxes forum a little while ago that the input cap is 22n But it seemed that along with the resistor change (low gain 1k, high gain 100k) there was a change of capacitor in the feedback loop (low gain 50p, high gain 100p) So your c22 is...

Yes, I’ve had issues with some 2.1mm Lumberg clones that didnt work (they did not look like 2.5mm, maybe just 2.15 or something) from various places (musikding in Europe, LMS in the US) It’s quite frustrating. There must be some QC problems somewhere in the factory that makes those clones.

Latest update to my knowledge: https://www.freestompboxes.org/viewtopic.php?p=271493#p271493 Input cap is 22n. Low gain has a 1k resistor going to lug1 of the gain pot, and a 50pf instead of 100pf cap in the feedback loop of the opamp High gain has a 100k resistor going to lug1 of the gain pot...

The Paragon has the optional charge pump (giving it more clean headroom), the Mini doesnt, I think that’s about it I dont think a charge pump is really necessary with this circuit, but its nice to have the option.

In this case the feedback is analog, it’s not part of the programming, so yes, a slam switch would definitely be an option. But with the various head configurations, the feedback pot always has to be adjusted, so it might not work out as well as you’d imagine

Hey, So I just finished my Hydra delay. It sounds glorious. I used A10k for the mix pot, and B50k for feedback (see below) I wasn't satisfied with the fact that with only one head selected there was not much feedback available. And when two heads were active, the oscillation could become way...

Glad you got it working! :)

If you have one repeat, then the chip is working Your feedback path is the issue I would think, not the chip You’re getting 8v on pin 3 & 5 of the opamp? That’s another issue, again not linked to the pt2399 Seems to me there’s some debugging to do here

The 4:1 is the best compressor I’ve tried. Stunning on electric as well as acoustic and various instruments. I compared it to the Diamond comp (18v) and preferred the 4:1. Ross based comps are quite colored, they dont work well with acoustic sources The Empress comp is amazing, but big and...

Hey, thanks a lot, that's useful information! Nice builds by the way. So no plate mode ever @PedalPCB ? :) I'd switch the room for a plate if I could...

Hi guys Just a quick question about the Spatialist reverb. I found a couple build pics online where the modes seem to include a plate reverb in 1st position. Was that a thing? I’d be interested in a plate reverb! Can we confirm that the modes, from 1 to 8 are as follow: Room Hall Chamber...

Very promising! Thanks for sharing. I'll order one for sure as soon as they hit the store! :)

@PedalPCB Thanks for the quick answer! :) Is the fixed modulation a light one (Im thinking like slow light triangle wave)? I mean, if I add clock modulation on top of it, will it be too much too soon? Thanks again. Take care!

Hey guys For those of you who have a D3lay pedal or have used this algorithm in a pedal, just a couple questions. I can't seem to find any demos or quick recording of it, so... - how is the tone? Is it quite dark, analog-ish, brighter? - how does the degrade pot sound? Does it roll of the...

Actually I find that with only one head selected, it wont go into self-oscillation. Same thing on your build?

In that configuration a 10kC with a 10k in parallel will work fine I think
