As always,
* Check the offboard wiring
* Scrape all track "gutters" clean with the tip of a knife. If your knife can get through easily, remove solder and redo that part.
* Measure(!) resistance between tracks for "invisible" jumpers
* Check component values
This is a verified build, so if you made your's properly it shoud function just fine!
There's also a hell of a lot of heat coming from where the 9v joins the board, Plus my LED doesn't work so do you think it could be a problem with the 9v/board joint?

Just Built this and all that comes through is noise, adjusting the pots changes the pitch, volume. Any ideas what might have gone wrong? Or any advice on how I might trouble shoot it? Thanks
i used it with a foxx tone machine but when connect the input and the input from the foxx it sound distorted.. when i disconnect teh input from the foxx tone machine it sounds clear ..
At this point, I can't tell you anything other than to 'experiment' with it! I built it once, it works fin, but came to a conclusion I like diode/opamp clipping more ...
You mention a possible mod for several resistors. Let's take R1 as an example. Would such a mod entail changing the value of R1 to for example 100K? Or even 22K? Is that what will influence clipping behavior? Or do I fit a 50K pot?
Harold, first up; great job on this site!
Secondly; is there any way you can fix those pesky ads that obscure the top right corner of the layouts?
thanks for all the work you're putting into this,

8.2k Resistance across the ground and positive power. Still a bit confused as to what i'v got wrong? Rechecked positioning to all components and trace cuts. Still have not a clue what i'v done wrong ha! I'll have to keep looking.
R1 's sole purpose is to burn up if there's a short circuit. If you measure between GND and +9v you'll get a very low resistance, which indicates a short circuit.
Check all components and tracecuts and scrape all tracks between the traces clean with the tip of a knife. If you can't pass through it easily with your knife, you should clean up the soldering.
Also check if the effect doesn't touch the enclosure!
I've got it all rigged up but R1 has turned into a burner...I'm not quite sure what the problem is? no noise, just a burning resistor. any idea why that might be? where i should i start debugging?
I replaced R2 with a 10K trimmer to fit the boost on my own taste... I like this pedal even more. Again thank you for this extremely good sounding layout.

working fine, a little distortion when you put the "delay" button between 80 and 100%
thank for your work !
Here is a discussion on how to get this to work:

No success yet...
Fun stuff is fun!
FYI: I started a new version this weekend. Fun stuff is ahead!
Thanks. I was just asking to make sure I wouldn't cause a ThermoNuclear meltdown... ;)

The effect eventually got recycled ;)

Yeah, hate them too ... ;)
Somewhere in the future there will be a completely redesigned site. As soon as I find the time! ;)

Finished building this today. Sounds great. I'm thinking of building another replacing the dip switch with 2 case mounted switches.

Do you know if this is a "Tall Font" or "Bubble Font" version? 2nd or 3rd revision?

The third row/switch of a 3PDT is used for switching the ground of a LED. A 2PDT or DPDT is enough for a true bypass without LED.
Hi thanks for your reply, although if not using an LED why the need for a 3DPT, wouldn't a DDPT be sufficient?
Thanks.
Works great!!! Thanks!
I always use a 3PDT like this: http://diy-layout.com/56
Hi can you please confirm what type of foot switch is required a 3dpt or a dpdt?
Thank you.
Thanks for the brilliant website!!
Only 1 question... does this pedal need a DPDT Switch or is it a different type?
Thanks again.
