The PPD shouldn't make any noticeable difference sonically. I can tell you that the layout does work and it's a very nice sounding overdrive. Triple check your work, you'll probably find a small error somewhere.
I've checked my work many times, corrected a few errors, but I'm still not having any luck. Bypass works fine, with switch engaged LED comes on but no sound. Pots don't do anything to the sound either engaged or not, even with the amp way up. I tried swapping the Volume 1&3 leads.
so I may not be able to help you get this particular layout firing, but here's some general tips that may help you in the future: 1) if you aren't all ready, use sockets for ICs and transistors and such. While you are new to this, you can potentially fry semiconductors by exposing them to too much heat while you are still figuring out your soldering technique. 2) look up some videos on youtube on how to build a guitar pedal tester box - that way you can see if the circuit is functional without having to wire up a footwitch, LED, jacks, etc. 3) don't give up - making circuits this way can be confounding and will test your patience constantly. I have circuits that I have built literally dozens of successfully, that occasionally i will still screw up horribly. It keeps me humble and honest.
I would agree with @Chris regarding the sockets...my first few builds I screwed up the transistor direction and could have adjusted easily if it wasn't soldered directly to the board.
I haven't built this one & I still mess these up from time-to-time but would also suggest you check the following one more time: 1) Did you get ALL the cuts underneath D3 and the 47r (and the other cuts for that matter)? 2) Are your round capacitors facing the correct direction? 3) Did you get all your links soldered in there? 4) Is your IC in facing the correct direction?
I'm using a socket. Cuts and continuity all seem good (verified with Multimeter) Polar caps oriented to the layout Everything soldered and checked for cold joints IC Facing the same as the drawing
I don't have a tone generator (think I'll just record a loop into a looper pedal) or audio probe set up yet (not keen on using my main amp for this purpose), working on getting that together.
Trouble is I've followed all of the "common troubleshooting" and "tips and tricks" stuff I can find, I really need help with this circuit specifically.
It's frustrating when they don't work. If you can, post a photo of the top and bottom of your build so we can see. I've put circuits in my junk pile just to pick them up months later and notice that I placed something incorrectly.
Neat! But the Input label in row I is missing ;)
ReplyDeleteTag it! Sounds nice and chunky 👍.
ReplyDeleteThanks you.

Excuse me, do you have the circuit or diagram of this pedal? I need to know how all those components are soldered..

DeleteUnfortunately I can't figure out how to post pics here, I may have to find a different forum to post to.
