  2. Made this one for a friends 10 year old daughter.

    It's in a Mini Lunch Box.

    She ROCKS like a Banshee now. LOL.

    THANKS IvIark!

  3. Thought I would add I'm using NPN GERMANIUM 2N1306 as the first transistor and 2N1308, 2ND.

  4. Here's the Classic Fuzz with all NOS components.

    OC75's and a SPRAGUE 22uF Titanium cap on the drive - volume pots. NICE.

    This baby sings...big time!

    The Hammond box is repurposed as it used to be some kind of video booster, so holes were already drilled in it. I found 3 of them for 3 bucks each.

    Check out the photo's, nice and clear.

  5. Hey EVAD, really sorry I missed these posts. It's only fairly recently that I messed with the settings so I'm informed of new comments so these were missed unfortunately. Glad you're happy with the build, and thanks very much for sharing the pics.

  6. Built this today and works like a charm sweet sounding Fuzz.
    Thanks Ivlark

  7. Any chance you could draw up a vero version? I'd love to build this guy.

      There's a schematic here? It's quite simple, so maybe you could try adapting it?

    2. Also, this is pretty much a modified Fuzz Face. Look up the layout for the Fuzz Face and you can easily change a few values to get the Classic Fuzz :)

    3. Thanks for the response! The PNP Fuzz Face layout on this site is also tagboard, not vero, so I unfortunately can't just layer new values and plug in the extra cap; a shame too, as it really is basically the same circuit. But you're right - building it doesn't seem terribly difficult in terms of logic and parts count. I'll break out my breadboard and finally use it :-P My main worry is burning out the AC128s/installing them incorrectly, as they're kind of expensive and I've never breadboarded a circuit before. Any suggestions for alternative transistors at the planning stage?

    4. Actually, I'm gonna ask a newbie Q: if I reversed the polarity of the circuit to make it NPN, would it have a noticeable effect on the sound? I'm trying to nail this thing, as I'm building it for a relative with very precise tonal prefs.

    5. I found this vero PNP Fuzz Face layout: http://static3.nagi.ee/i/p/609/11/15227811ed62e0_o.jpg

      Turning it into a Classic Fuzz seems like a fairly easy resistor/cap/pot swap job, but a question: where would I place the .0022uF cap connected to the (47k) Volume pot in the Classic Fuzz schematic? The schematic: http://experimentalistsanonymous.com/diy/Schematics/Fuzz%20and%20Fuzzy%20Noisemakers/Roger%20Mayer%20Classic%20Fuzz.gif

      And the original Fuzz Face schematic for reference (Volume pot is 500k): http://experimentalistsanonymous.com/diy/Schematics/Fuzz%20and%20Fuzzy%20Noisemakers/Fuzzface.pdf

    6. This is pretty much a PNP FF, with also slightly changed values!

      http://tagboardeffects.blogspot.com.au/2014/07/dunlop-jbf-3-joe-bonamassa-fuzz-face.html

      Just try following the input of the circuit and through the different components and check this against the schematic. It can be kinda confusing but the FF circuit is a good start.
