2399 LoFi Delay
Assembled Unit:
The *NEW* PT2399 LoFi Delay module features professional circuit board and high quality components. The Delay effect simulates tape-like analog stretching and gritty artifacts at low speeds with excellent crisp echo effects at short delay times. “Infinite” repeats can be achieved with feedback knob control. Easy to assemble and integrate into your existing musical instrument. Direct Piezo, guitar, line audio input without any required amplification.
- Professional High Grade circuit board
- High Quality box type capacitors
- Sealed potentiometers
- Quality switching jacks
- Socket for the IC
- Heavy Duty voltage regulator
- On board power indicator LED

Easy to build echo/delay circuit with a PT2399 digital delay IC. Time stretching with "infinite" repeat abilities for analog feel. Professional through-hole circuit board. Works great with Piezo microphones, guitar signal, voice, and more. Assembly required.
Price: $35.00
Demo:
When can we expect the revised version to be up? the current schematic looks a bit dodgy, and I think there are quite a few of us who are eager to see it released!
The new version will be up as soon as I have enough funds to produce the boards. The production is really tied to shop sales. Hopefully within a week.
Well cant wait for the new delay boards.
Any new updates on the current project? Have not heard anything in two weeks
Any progress?
I tried putting it together using the above diagram on a breadboard. I get a clean audio signal when I play through it, pots have no effect… except the 250 pot when turned all the way up produces a high pitch tone. The high pitch tone can then be adjusted from the speed pot. BUT, no delay. Wish there was more to go on to diagnose the issue. Please post build instructions, a real schematic, or if nothing else… sell the old kit again.
I have been checking back to this page for some time now, as I am sure MANY others have as well. It comes up first on google for “simple delay kit” etc It’s time
HELP! thanks
Hi blankeinstein,
Have you got pictures i might be able to help you out.
my email is……. vimal1@hotmail.co.uk
What type of noise does it make????
Hi blankeinstein,
You could contact circuit master they are very good in helping you too.
i had the same issue that blankenstien has. though i’m not the best solderer in the world, but i was getting nothing out of this. i would love to buy the kit to really figure this out.
SÜPER DELAY
Hey, thanks for all the comments
I can take some pics of it.. it’s just I built it on a small breadboard, so things are a bit cramped to see in photos. I have gone over it 5 times now, rebuilt it piece by piece, triple checked everything… still no good. I have built way more complicated pieces than this. This delay is only like 15-20 components! lol
Then again… most of them had rather clear schematics. What would REALLY help is a look at what the BACK of the PCB looks like. That way I can at least reverse it and see if I am running a lead somewhere wrong.
I built the quad oscillator synth, went really smooth.. EXCEPT for the leads hidden under the IC. CircuitMaster likes doing that
I was able to check my traces from the photo of the back of the PCB.. and you know what? There was a trace going to the left, that I thought went all the way through to the other side of the IC.
I am almost sure there is something like that going on with the delay… any comment CircuitMaster? I hate dead breadboards, keeps me up at night in bed! lol sad part is I’m not even joking
thanks again all…
Blankenstein
So have you got it working blankenstein???????
Am waiting for the new board…………..looking forward to that.
Nope, she is still dead… :-/ It was the quad synth I got working.
I am at a brick wall till I can see the traces, or a schematic…
CircuitMaster where art thou’ ? lol
~Blankenstein
Blankstein send me an email with piccy so i can try to help or i can help if i could ..
You have my email.
And keep trying to contact circuitmaster they are very, very helpful too especially Alex the circuit creator i believe.
cheers
I’m also curious when this will be back in stock and available to order. I’m looking at getting the distortion lab & the delay kits, but I’d like to order them together.
ok vim, i’ll send you some pics of the breadboard. I will try to spread apart the resistors so you can see what’s going on.
CircuitMaster should check his blog more often and get this kit out
He is clearly missing out on some good loot here… lol
Hi Blankeinstein ok.
Circuitmaster should start picking up emails for helping too.
cheers all
How much longer we lookin at for the new design to hit the market?
There are some in the web store now, however they are nothing like the image on the website. Need to do some updates and tweak the circuit board.
Hi all Just once again if anyone wants help with this then email me so i can do my very best to help you out.
cheers
Hi! I’m completely new to world of DIY pedals/toys etc… and it’s a bit of a dream of mine to start. I was just wondering if someone could tell me if this kit comes with any form of instructions or help with the build. I’ve soldered things before, but I am not very experienced. Is this a good place to start, or would it be a bit over my head? Is there anywhere I can buy a complete kit of tools I would need to get myself started? Sorry for all the questions!
Cheers
Ben
Could you please email the schematics for the old kit?
Thanks!
Django
hi circuit master how can I control the delay time not the repeats.
ie which reisitor so i need to change so i get less of the msecs rate????
cheers
The delay time is controlled by the 250K potentiometer.
Hi Alex,
I know but I want the delay time to be less from the start. which pin of the pt2399 controls the delay so i can change and add a resistor for it to start from a shorter delay.
regards
vim
Hi Alex,
what about wet and dry control would that be possible to add on your design???? If so how is it done????.
regards
vim
Is this kit still for sale?
How much delivered to UK?
Any other similar kits or pre-made audio delay modules?
Cheers
Tony K
Hi Tony try contacting me i might be able to help.
good delay sounds wonderful and very simple but yet so powerful.
circuit master do sell them, they are in the states.
very nice people.
Hey man, you getting more of these delay kits in?
The first delay board batch sold out fairly quick, some minor tweaks will be made to the circuit board and we’ll be able to do a next batch with production quality green circuit boards. Silkscreen and all. Thanks for the support.
Anyway you can send out an e-mail when the new delay kit is available?
Or e-mail out a schematic/parts list? Thanks!
Hi if you can email at all when the new kit is available then i’d love to grab one. Thinking of building this into some spare panel space on my synth
Ahhh can’t wait. gonna order as soon as it becomes available!
Will this PT2399 delay kit ever be back in stock? Hope hope
I almost have them. waiting on some capacitors to complete the kits. the circuit boards did work so its just a matter of getting the remaining parts.
any chance of sending CV to the settings on these? I’ll order one anyway, but that would be awesome
Is it possible to use a 3PDT for the power switch?
