Creepy Fingers FuzzBud

Here's a great sounding one-knob fuzz from Creepy Fingers Effects for your FuzzFriday. It's based on the fuzz section of the Colorsound Fuzz-Wah and follows the basic structure of the Fuzz Face, just with a fixed resistor in place of the fuzz control. Shouldn't be hard at all to fit in a 1590a enclosure.

  1. Just verified! Awesome sounding little fuzz and super loud with the two 2N2222's! Thanks man

  2. Cool! Thanks for verifying, Charlie.

  3. No prob! One question though. Do these transistors have to be matched?

    1. It's a fuzz face derivative, so I'd start with a higher hfe on Q2 then experiment a bit.

  5. I builded this pedal and works fine, thank for effectslayouts.blogspot.com.br!!!

  6. Built this but with 50k pot even at very little it is very very loud. So i cant get much range. if i turn it all the way it has no output but touch the pot even a little and it roars is there a way to control this to get some range that i can use.

    1. Did you try any different pots? Increasing the value should give it better range. Try 100k or 500k

    2. using a bigger value pot seems to have no effect at all. correct me if im wrong but would using a smaller value pot allow more signal to be shunted to ground that lowering the overall output?

  7. Built it, awesome low end strong drive, like it very much,
    thanks for the layout..here share my board: http://i1244.photobucket.com/albums/gg569/pakkee66/DIY%20PEDAL/FuzzBud_zpswliul8w6.jpg

  8. So use a B50K pot? I think the poster above had a bad one.

    1. Use a 50k and if you don't like it try 100k or higher. YMMV

    2. Thanks. I bought a 100k also. I have some 250k pots from my telecaster project. I'll try them out.

  10. Is there a recommended parts list out there for a burgeoning diy pedal builder? Maybe even some recommended components for this pedal? Thank you!

    With L-U-V,

  11. its says fix resistor in place of a pot for fuzz control. which resistor is that so i can experiment with pots

    ReplyDelete

    1. The 1k resistor off the emitter of Q2. Though you'll probably want to remove the 10uF cap that's in parallel with the 1k resistor and run it between lugs 1 and 2 of a fuzz pot (negative lead going to lug 1 of the pot).

  12. I have verified this pedal as working..I used a B-250k pot . I made 2 of them first one with vintage can style transistors and second with modern plastic ones. I think the old can style sound better. what is the difference if any? am i wrong? also the only other difference would be a 1.2m resistor instead of 1m i was out? would that make the sound "thinner" it seems lacking in some way compared to the other one with can caps? thanks for any response. peace

    1. The 1M resistor is just the pulldown resistor so your footswitch doesn't pop, so using a large resistor isn't hurting anything. What's you're likely experiencing is the tolerance in caps. Most film caps have a 5-10% tolerance and ceramics around 10% or higher, meaning that the value will be with that percentage range. So between your two builds some of the caps may have been on the lower end of that range and others on the higher end. That'd be my guess anyway

    2. thanks man! hey do you think i am off about the transistors? thanks

    3. I would expect some variance between metal can and plastic packages, but again, nothing too out of the ordinary. All BJTs regardless of package have an acceptable range of hFE that will vary from transistor to transistor. All that to say, the transistors will play a role in the difference between the two, but I would think the capacitors play a larger role.

    4. I changed pot to A-10k it seems to work better...not so slamming loud right out the gate..and not as much noise. thanks for the help

  13. How can i add tone control i this?

  14. Working perfectly with 100K pot here. Thank you effectslayouts.
