make sure that the pin 4 of the pt2399 is connected to the ground.

Usually this issue is related to not having the pin 4 properly grounded which makes the pt2399 lock.
Verify/correct it and report on the results.

No problem my friend. I'm wondering that maybe this is a problem related to the power supply. I'll try to build one and see if it still happens.

Tks anyway.

so long as I got the pinout correct (since they're kinda opposite from an lm7805) I've never had a problem with them on pt2399 builds.. done dbd, echo bases, heaps of rebotes.. never been a bother. Hi Guys, first of all, tks for bringing all this great pedal! I've built mine using both my own draw ...

If I plug a humbucker to it I get much more repeats and it starts to oscillate much earlier, maybe around 12 - 1 o´clock. With a tele it starts to oscillate at about 3 o´clock and with my acoustic guitar I can´t get it to oscillate at all, even at max repeat. Strange, it seems like the impedance of...

Anyone have an idea what can cause the repeats on my build ( it´s from Ivlarks layout) to behave differently depending on what I plug into it? Could it also be a bad pt2399? I´ve ordered some more from a different supplier so I´ll try that, but any input would be useful. I get 5.07 V from the 78l05...

Hi guys, for those who are getting often only clean signal from the DBD I would suggest you to try a different voltage regulator from the suggested 78L05. This are really crappy ones and are not that stable. I've made a test using a LM7805 (1A) and It worked very well and in a Robust way. I also tes...

I made lVlark's layout. But the problem is on all 3 boards I made, I get clean signal with the volume knob working , nothing else is working and there is the clean signal even with the PT2399 removed from its socket. What could be causing it? I checked row 7 of the layout which has a trace cut and ...

Hi Guys, first of all, tks for bringing all this great pedal! I've built mine using both my own draw board and meadbeans one (all of them using madbeans schematic) and I found a funny issue on them. All that I've built sometimes work and sometimes not. First I tought that it may be related to the PT...

I just did the R18 and Cap mods, didn't do the diode, and it is a amazing change. I always liked the pedal, but this makes it breath so much more. It gets a better quack and the knobs seem to be much more responsive overall. Thanks for the tip. :applause: looks intersting . I'm very unpleased with ...

Man, you rock!
i've always been looking for a good, reliable and 'little' vibe project. This one is perfect!

Thank you, and congratulations...
do you have any tips for somebody that wants to create a new layout for it?

oh, i almost forget. Your layout is awesome!!

thanks.
