JHS Angry Charlie

I've gotten a few requests to redo the MI Audio Crunch Box with board mounted pots. How is that relevant to the Angry Charlie you ask? Well, it's the same circuit. JHS added a cap in parallel with the existing cap coming off the Presence control to ground which tames some of the highs. So if you want the Crunch Box, just leave that cap out.

  4. For anyone who's adventurous, I mashed up the Angry Charlie/Crunchbox with the original Guv'nor tonestack. Christened it the "Dirtbag". Will be verifying this tonight:

    All tone pots are A10k, B100k for Vol/Gain.

    1. It's verified. I really, really like this version. I find the tone stack to be a lot more flexible than the Angry Charlie/Crunch Box. I just kept wanting a bass control. Plus this one lets you scoop mids and get a pseudo-metal sound.

      There's not a TON of volume in the pedal, but it gets above unity even at minimum gain settings.

      The clipping LEDs light up quite nicely so it's a good candidate for mounting them in the enclosure.

    3. one more to clarify, is that 2.2uF above the IC a ceramic or elco?

    4. I used a Tantalum cap there because I had it on hand. You can use that or an electro.
