Did you mean to say that the 5th cap goes to j 28 to j31 insted of  J26 and the other in J28?

good catch!  i meant to say J29 to J31   :icon_wink:  thanks, bro!  :icon_biggrin:

EDIT:  ok, fixed it.

I'm doing a uni project on a distortion/overdrive pedal (Something like Visual Sounds' "Jekyll & Hyde") and this looks like just what I need! I've only had a 10 minute skim over the four sections, but you've managed to simplify to a level I can actually understand! :icon_lol: Thanks :)

Looks good thanks. You can use that as a stripboad layout if you cut a line of holes across the stripboad. Not optimal, but at least it will work the same as the breadboard.

cool.  :icon_cool:   :icon_biggrin:

fwiw, in this thread [Vero?] i through together a sketch of an actual stripboard layout.

all the best, gm

I did it :D.... finally...

Here in my town there aren't any big stores... only small, old-fashioned electronic stores, and I had to go to all of them to find the pieces....

And since I was a little disappointed on how the beginner's project worked for me, I wasn't really sure how this was going to come up.

But I finally finished It, it sounds great, thanks to all the people that posts here  :icon_biggrin:

This is excellent!
This is the only article I've read that actually explains the parts, their function and their relationship to one another.
I found a breadboard on the net and I'm waiting to try the things you have shown me.
It will be great to try things before soldering them.
Thank you!

Thank-you for this great tutorial.

I methodically put it together on the breadboard, following your instructions.

When I tested it without the diodes, it worked and I heard distortion. After I added the diodes, it also worked and I heard distortion.

But then suddenly, it went back to simply hearing a clean sound. Any ideas what coud have caused this?

Questions:  1

I am thinking that perhaps it was a breadboard connection thing. i don't cut the legs from my resistors and capacitors, and thus they often dangle on the breadboard. I wonder if something like that a happened?

Question 2:

I also wonder what kind of capacitors are being used here. is there any way to specify whether a film electrolytic or ceramic capacitor is being used? Maybe that also caused my problem- choosing the wrong capacitor type?

Question 3. Is there a chance I blew the op amp? How would I know?


Thank-you for your help and expertise.

Have you tried whacking your breadboard?  :icon_mrgreen: :icon_lol:

Cap types shouldn’t matter, as long as the values are correct, power ratings not lower than your PSU (which should be 9v) and as long as you get the polarity of electrolytics correct, otherwise they heat up and explode.

If you swap the op-amp and it works, then that’s it... otherwise get some voltages... :icon_biggrin:
Happy Sawdering!
