Buddy's Breadboard and Circuit Design Notes

Removing Q3 and the circuit is much too quiet compared to the others in my project. Removing Q2 and there's not as much compression/clipping as I'd like. Would it be worth throwing a resistor before Q3, say, 10k? It doesn't sound bad to my ears...
 
Try the resistor and see if you like it better. Do the same thing between Q1 & Q2. Without the series resistor, Q2 interferes with Q1's soft clipping. Same goes for Q2 & Q3. The way you have it wired now, the clipping is very asymmetric. But whatever sounds good, that's what matters.
 
Here's the second iteration. It's much more standard Muff than I realized. I threw back in the 4148s instead of the LEDs. Having only 1 clipping stage only give me a hint of muff, so I really needed the second stage. This reminds me of the creamy, classic Muff sound. With the tone shaper in front of it there's really no need to tweak more cap values (although maaaaybe C1 to tame some of the low end a bit). I guess the real challenge now would be to put this on as compact of a stripboard build as possible...

A hint of muff?
Like a tinge of minge?
Now that's a pedal name!
 
Here's the stripboard layout. I want to look at this with fresh eyes tomorrow to visually verify before committing to solder. If anyone sees anything wonky let me know. I tried to make this as thin and dense as possible. I do have a slight real estate constraint in the enclosure. Some free standing resistors, but I can live with it.

Thanks. I was worried about some of those standing resistors. Turns out you can just bend them down. I’ll wire it up tomorrow and hopefully it works the first time.
 
Ya know Tayda sells 1/8W 1% resistors. Those are my preference because they easily fit even the tightest boards. I like the bigger 1/4W resistors for breadboards.
 
Yea, I know. Long time ago I decided to make 1/4W the standard in my inventory. I do have a few baggies of 1/8W from other builds.
 
Wired up and works just fine. Had to troubleshoot it for a moment since I didn't solder the input wire very well and the signal sounded "starved". But she works! Here's my completed build. It's a 5-in-1 (geez...)

Buddy's Mega Dirtbox - Working Prototype

This build was started with a shower thought about 3 months ago and I asked you guys about it here. https://forum.pedalpcb.com/threads/eq-before-and-after-a-circuit.21689/ Then I set out to build a "Dial-a-dirt" + Booster/Tone Shaper. TL/DR this is a 5-in-1 combo build for all kinds of dirt in...

Hey Chuck, I took your advice on the integral preamp to convert to 9V. I think I may have botched it. Now it’s just a very dirty boost with little too tone control. I may put this back on the breadboard for a stripped down version. Shouldn’t be too difficult. I can always put it on vero.
