The PDS was boxed with the PDS manual. When I got mine, I thought I got a PDS manual by mistake, so I called digitech and. I am fond of the Dod/Digitech PDS series delays. On paper there’s nothing too amazing – mid s 8-bit delays with 1, 2 or 8 (if you can afford. DigiTech PDS Two Second Digital Sampler: DigiTech PDS series» digital delay pedal», sampler pedal».

If it let me go So once in Trigger mode, you must press the switch on the left to launch a sample. Once the recorded phrase, therefore, we must switch to “Trigger” ie bending, super convenient Mateusz Rademacher 25 April at I haven’t seen a schematic for the PDS 8 second delay.

I already had an analog delay an Ibanez ADso I was pretty used to this kind of sounds. I would like to see how this was implemented, as it should have 4x the memory of the PDS Ja zehre a Chance that i could send oh to you for repair? Mamual best picture I can find online shows a single 18 pin not 16 pin IC, but the label isn’t legible.

I replaced the trimmer and set it to the middle of the it’s range, based on how digitecu other was set. I repaired 4 of these delays recently.

Re: Digitech PDS8000/PDS2000

This actually worked pretty well, but replacing these pots and running wires to the PCB is probably a better long-term solution. This pedal may well be digital, it can become self-oscillation, which is very cool.


This PDS mine was fairly easy to deal with. Do you know where I can reorder it and which exactly to get? Anyway, it’s extremely complicated to use for a result frankly not great With the new chip the delay rates could be carefully dialled in to 2 seconds pretty quickly. I ordered a new 74HC04 and got two working pedals. The delay loop in the PDS series is basically digitexh ripple counters counting through memory addresses and resetting when the end of memory is reached. This was in the worst condition.

I am pretty noob at this but I know I can resolder it First you must get in Sample mode which works like Normal modeswitch the pedal, play a phrase when that phrase is repeated, using the switch on the left to bring it into memory. Finally, a tribute all the same to the ancestor of the JamMan!

Dibitech i got sone issues with my pde There may be an “official” method for adjusting maximum delay length using a testpoint on the PCB but 2000 a service manual I’ve come up with my own. I think this will only work well for very dgitech sounds, as the sample rate will get much lower and aliasing effects will get worse. Tweaking these delay pots brought the delay back to 1 second and adjustable through the full range of the delay pot.

Most of the tweaking is done on the lower global clock frequency trim, usually after making sure the delay pot is working throughout it’s whole range.


Extending the to 8 seconds may be possible depending on how extensive the differences are. This one was partially working when I got it. Another thing to note is that the pedal off the sound for a short period of time when using the switch Write manuql user review Ask for a user review.

With Infinite Repeat function and the change in pitch when you move the knob Delay Time, There are enough really fun!

Produced in the 80’s, one of the first of its kind! I messed around with compounder trimpot as I thought that may be distorting – no improvement. Everything is done with standard CMOS logic. Here is a braindump: I got this in a box of failed repairs from a music store in the US some years ago and never did a lot with it until now.

The footswitches were also unreliable, so I replaced the microswitches. Raju Solanki 16 April at This is on purpose, but it’s still boring. In contrast, we try to use the sampler mode, the problems appear.

It is the ancestor of what JamMan. The mznual trimmer for clock frequency was also broken off.
