My new circuit - "1983 Fuzz" Old School Atari type fuzz

[timd]

Here is my first circuit. I named it 1983 fuzz because it reminded me of the sounds of Atari/Colecovision from the early 80's. I prototyped it on a breadboard, then wired up a permanent copy and it works great!

[rutabaga bob]

Any sound samples forthcoming?

[petey twofinger]

cool !

+1 on the samples wanted

[timd]

I'll see if I can get something on Soundcloud tomorrow.

Love how the 80s computer fuzz has a 386 in it

[timd]

That's hilarious - I never though of that. My first CPU had a 486sx in it...sound clip coming very soon!

[timd]

Here it is!

The last few seconds of the clip really show the old school quality I love about the pedal.

Oh, if you plan on making one, the 100 ohm resistor from the power supply might not be needed. On a breadboard, it worked fine without it. Once I soldered my circuit, it kept crashing on me about 5-10 seconds in. I added the 100 ohm or so (I think I settled on an 80) resistor, and it worked fine. Weird.

All of a sudden I feel like a 5 year old playing video games again.  I'll have to give this one a shot one of these days.

Please do! Let me know how the build turns out - its fun and pretty easy! Also, if anyone has any suggestions, please let me know!

1983...(A Fuzzbox I Should Turn To Be)

[petey twofinger]

one of those sounds was similar to the 2600 game "raiders of the lost ark" , the noise you get when indy dies .

thanks for sharing this , at some point , when i get time this is goin on a breadboard .

[timd]

That's great stuff Petey. I finally completed a circuit I was proud enough to share, and the sharing/helping nature of this forum is tremendous. You should build the 386 Fuzz. I cannot stop playing mine and now the bass player in my band wants one too - it sounds great with guitar or bass.

[petey twofinger]

thanks for sharing that man .

i actually have a 556 chip or two here , and the 386's as well .

its on the list , i want something like that just for "fun" . circuits like this get extra bonus points from me cause they are exactly the opposite than the typical attitude of " i need a pedal to nail the sound of my dimed marshul" .... "sustain for days ? " you'll be lucky to squeeze an 1/8th note out of this sucker

Yeah, when it comes to circuits, I can often be "against the grain" in my search for new and bizarre sounds. That's one of the reasons DIY pedals really got me going in the first place. Because of demand, major pedal manufacturers don't waste thier money making "fun" or "strange" pedals. You can do what you please if you do it yourself though....to an extent.

Holy godder of mom! I'm in love!! 

[petey twofinger]

OT , but yesterday i accidentally "figured out" how to mimic the "Pac Man" death rattle , using a sustainiac , high hain distorion and the whammy bar . i lolled .

seriously OT , i read in an adrian belew interview he said when he was a kid he saw Maury Ampsterdam on the tonight show goofing off doing sound effects with a cello . he said he did seagulls and something else . that is so awesome .

[Ultrakd]

awesome!! im gonna build one....or try lol

[Colonel Angus]

That sounds rad! I just ordered some dual timers too

[timd]

Let me know how the build turns out! I had an idea about adding another 556 chip in the design with 2 more pots, but I don't know if the signal will reach that far. I might have to add another 386 too.  Any suggestions?

I'll be making/posting a youtube video of the finished in the painted case version hopefully early next week.
