Looking for opinions/suggestions...Best PT2399 Delay

[SQ1]

Give me your best delays, looking to build just one for a future board

looking to build just one

PPCB Magnetron is nice

Tape Delay mkII from @Aleph Null is also cool.

 

[SQ1]

Yea that Keeley one is nice, definitely a contender

 

[Alan W]

I’ve been very happy with the Seabed.

 

[SQ1]

The Mad Professor was the first delay I ever built many years ago, that was great

 

[phi1]

I like the Seabed too. I designed and built this to get Sea-Bed tone, without any noise, and also adding modulation. But, without this build I was still digging the deep blue circuit.

Thread 'Deep Blue Delay Simulation (FV-1)'

Nov 19, 2023

I finished up a pedal that I’m pretty excited about. It's a FV-1 implementation of the Mad Professor Deep Blue Delay, where the FV-1 handles the delay time and modulation, but the filtering is analog circuitry around the FV-1.

The DBD clone was the first build I attempted, first try (on vero) went in the trash but the second try worked great. At the time, I had read a lot of great things about it and I still do really like the tone of the repeats, which filters both high and low frequencies. It's been my favorite sounding delay circuit, and I'd encourage anyone to build it as is.

On the magnetron is it basically the same as the Mad Professor Blue delay when the depth and speed are on the lowest setting

Yeah it's similar but the filtering of the repeats is a bit different, I think just personal preference. I can see that the R and C values and some of the signal routing is different, but I haven't built the magnetron to compare how different it actually sounds to the Deep Blue.

Pelota2 is my fav.

 

[Ginsly]

I'm sure there are a zillion more recent (probably improved) versions now, but I find the Rebote 2.5 delay pretty fun.

On another note - what's the consensus on Tayda PT2399 again...? I still have a few of those, although I'd certainly opt for using ones from Robert. Seems like they're not fakes necessarily, but maybe a bottom of the barrel, crap shoot kinda situation?

I've bought cheap 2399s and I've bought expensive ones. Honestly, I can't hear a difference; they all start to get noisy if you ask more that 150ms of delay from them.

Thanks - this is very good to know, and kind of why I ask! They have a lotta grit once you pass a certain threshold, so I figure it can be tough to suss out "good" from "bad"... I assumed the "bad" ones or fakes had a higher noise floor, no matter the settings.

 

[JTEX]

The PT2399 noise/grit at longer delay is quantisation noise (error) due to the low amount of on-chip memory being stretched too thin. If you want to use longer delay times (say 0.3s or even 0.5s) without excessive noise, the best you can do is to limit the chip's bandwidth (darker repeats). I happen to actually like the darker repeats, so it's a good tradeoff for me. YMMV.

 

[iamjackslackof]

Personally I've never built a PT2399 delay that I didn't like. All of them sound good to me, assuming you use legit PT2399s, and you go through several to make sure you're sounding as good as possible. I own multiple real tape echos, and am a big fan of the PT2399!

Specifically, Pelota2 is good, Seabed, the Keeley one, Rebote. Probably others I've forgotten.

Another vote for the Magnetron, my go to for any pedalboard build. There are a couple mods you can do to get some more utility out of it.

The Magnetron colors my tone, so I choose the Seabed

 

[owlexifry]

+1 Sheepylove Pelota2 (build report pending)

 

[zeropluszero]

Magnetron or Tape Delay mkII from @Aleph Null

 

[anevilspar7an]

The Magnetron colors my tone, so I choose the Seabed

Colors it in what way? I use active pickups in my basses and guitars so I don't hear too much change to the base tone under the modulation. I would assume since the PT2399 has such low memory you would get darker repeats without an emphasis filter in the delay signal only.

Troglodyte Reverb by @Aleph Null. Contains a Belton brick as well.
