Duuuude! How did you get those clear slices in your enclosure so perfect? I would love to try something like this if you happen to see my reply. I just checked your video out and I have stumbled on your youtube previously too. Kind of neat!
Well, my two cents... If anyone get problems with TL072 (under unity kind of stuff), just throw a LF353 in (as I did) and the thing comes alive. Another great layout, mate. You're becoming a top master in 2399 territory! :O) Cheers!
Hi Ian. TL072 is a jfet dual, the same with LF353. Both are cheap and both can do the job, and both are easy to buy. You can also put a OP275 (or AD712, or...)in. But you'll have to pay a lot more. Myself, I started with LF353 and ended with OP275. Not a very noticeable upgrade, if you ask me. If I can give one small advice, here it is: always socket ICs (and trans); and try diferent ones, to taste. The most important factor to your pedals is not other guys opinions, but your own ears.
I built this and it works really well when I have another pedal in front of it but for some reason when I plug my guitar straight into it I get an unreal hum/screech when I engage the Circuit. Any ideas?
I tried a few other pedals and seems to be buzzing with any pedal other than the looper I use to test pedals with my audio probe. Even if looper isn't on I get no buzz if its in front of the delay. Any other pedal in front on or off gives a buzz.
I am far from an expert on the matter but to the best of my knowledge the PT2399 only really stays clean for relatively short delays. I -think- in order to get a longer cleaner delay (with this chip) you would need to build a delay that uses more than 1 PT2399.
Another thing to consider is this is supposed to sound pretty analogy and the repeats are supposed to degrade so to some degree some of the noise is kind of a feature.
If you happened to learn anything since you posted this I would be interested to know what you learned!
Hi, nice pt2399 project - haven't got much noise or hiss in any settings, except with infinite repeats, but that's to be expected. I like it, very clean! Thanks for the layout!
I just wanted to chip in how much better by comparison this is to the mosky deep blue clone I've been using all this time It's like it's really open compared to the clone. The sound can breathe. It's also really easy to control the oscillation... And it really happily sits on the edge of infinite repeats.
If anyone is interested in adding modulation to this delay, the Deprofundis daughterboard does work well. A small modification has to be done. Delay 2/3 connects directly to pin 6 of the PT2399. The 2.7k is then moved to Delay pot 1 to ground. I eliminated the chorus without delay setting by disconnecting the daughterboard connection to Delay 2/3 (and used a two position switch), as it had too much latency for my liking. Pretty cool. Subtle to Echo Dream II type mod weirdness in slower settings.
This one is good to go, man. The repeats are so clear.

Thanks mate. Sounds good! I'll tag it.

DeleteGood layout, thank you. But unless i'm missing something the picture is smaller than usual, isn't it?
ReplyDeleteFixed. New Blogger software seems to have some bugs. Switched back to old Blogger and the linked images is now in original big size.
Deleteperfect, thank you!

Is it safe to put a jfet op-amp in here? (Forgive my ignorance, I don't under this stuff, I just paint by numbers)

DeleteThank you dragāo. I often read your comments and I value your input!
DeleteI've got it up and running with a TL072
and it's doing well! Exciting?

DeleteThank you very much for this useful article. I like it. delay pedals for metal
ReplyDeletehow to get rid of noise(hiss) in longer delays? please help!

ReplyDeleteHi fuzzhead.. just wanna make another LED to blink with the tempo of delay . Can I make it ? Best regards

ReplyDeleteDone! Here it is!
ReplyDeleteIt will trail for longer than my mosky...
Sounds great!
My first non Fuzz build!

Just beautiful.

ReplyDeleteI see. So that led is for marking repeats of the echo?
DeleteNo, the LED is your regular on/off bypass LED.
