CONTEST What? Another Contest?

[Chuck D. Bones]

I finished fooling around with the Deuce-Deuce, here's the final version. I got rid of the mid-scoop. Q200 goes where D3 or D4 would normally be installed. Fairly smooth distortion at low DIRT settings, gets good and raunchy at higher DIRT settings. This pedal has plenty of gain, plenty of volume and likes to make feedback. Some folks might prefer the DIRT pot to be B-taper.

Breadboard pic or it doesn’t count!

Ha ha ha ha ha ha. I can't enter my own contest. Wouldn't be prudent. Besides, I already ripped up the breadboard so I could move on to the next project.

Can I borrow your riding mower?

Oh I forgot to post the schematic for the daughterboard I used on my build:

You might want to add 100nF film across C1 and C2 to filter the HF crap.

Dude. I have a tractor and lots of implements....long story......previous hobby....

Solid idea. Never personally had any issues as it switches around 40kHz and runs dead quiet (especially compared to transformer based supplies), but couldn't hurt for sure.

I’m not gonna make it, I still don’t have my computer back from the repair shop — all my build notes are on it.

Why not check with the NSA? I'm sure they have a copy of your files.

I finally got around to breadboarding Dan M's TremFuzzolo. This little circuit rocks!
I couldn't find my 2N6027 PUT, so I subbed a vintage 2N1671B UJT. I had to take some liberties with component values to get the UJT and JFET dialed-in. I crammed this circuit in the corner of a breadboard that contains Jubal81's FuzzDuster. Pink knob is SPEED, red knob is DEPTH, VOLUME knob is out of the frame. The black TO-5 can at the bottom of the pic is the 2N1671B oscillator. Bottom left is the 2N5089 voltage-controlled resistor. Just above that and a little to the right is a 2SK193 JFET output amp and a little further to the right is the MPSA13 fuzz-maker. I got the desired speed range without the need for a toggle switch.

Well done Dan!

Thanks Chuck. I think I’m going to box it up, I just haven’t figured out the enclosure color yet.

Many years ago, a friend of mine had a Vox Repeat Percussion. Similar circuit to your tremolo section. I was not all that impressed with it then, but I like it now! Does a good job of simulating an echo's decay envelope.

BTW, you need to delete C202. Q4-G needs a DC path to GND. Once you fix that, you might need to tweak R22.

Thanks It sounds a lot like the Soldano GTO which is what I based it on, though frankly I think the original tonestack was more useful than this one. I finished it at midnight so I didn't get any recordings last night, I'll see if I can get one tonight.

Get me all worked up like that and leave me hanging?…. Not cool man…. I needs it!

Crap, my apologies. My memory isn't what it used to be. I'll try to get a recording tonight.

I couldn't find my 2N6027 PUT,

So you forgot where you PUT it?
