Earthquaker Hizumitas

 From the source:

The Hizumitas was designed for the one and only guitar sorceress, Wata, from the legendary band, Boris! We could not be more excited to have the honor of working with such an iconic legend known for her crushing riffs and mind-melting leads. The Hizumitas is a faithful sonic recreation of her go-to distortion which has been a staple of her tone for many years: the Elk BM Sustainar.

Despite the claims it's not a 1:1 clone of the original, as there are some changes, but who doesn't love a BMP variant. The only change from the schematic is I included a polarity protection diode and 100uF filtering cap in place of a 100r resistor from +9V to the power rail. If you want to include it swap out D3 for a standing 100r resistor. Build on fellow followers of the fuzz.

  1. No way I was going to buy one of these. The Boris video is awesome. I might need to build this one, however looks very similar to the cloven hoof...

    1. Replace the 39k on tone 3 with a 2-3k resistor, move the leg on the top row down one and add a cut behind it and run that row to leg 3 of a 25k pot. Connect lugs 1 and 2 of the 25k pot to ground and boom - shift control just like on the Cloven Hoof

  2. Damn, this year is starting off pretty nice. I wondered how they tweaked the Elk sustainar. I knew it probably wasn't to be 1:1 with the schematic on Kit Rae's big muff page.

  4. Is that Mid Swtich an On/On/On or On/Off/On?

    1. It would probably be on/off/on so you could switch between the boost or scoop or just as effect is without....

      I have got most of the parts for this and have started building, hopefully I'll be able to verify. I reckon it'll work based on the fact the cloven hoof worked from this page.

    2. on-off-on, just like all the other BMP variants posted that have the added mid switch

  5. I think you're right about the On/Off/On switch. I poked around some other BMP-based circuits that use a center Off switch (Colossus and BYOC Large Beaver).

  6. Ok - I have made the circuit on vero. Just need to add the control pots tonight and then test. If all working I'll have a vid up soon, but pics will be on my insta unholy8155. Cheers for the layout Zach.

  8. Sorry blogging ID was doing something odd, I wrote a big post and then it didn't upload so just wrote verified.

    To go into detail, I built the version without the switch, I will add the switch just don't have the parts to hand right now.

    The effect sounds awesome, i tested it thru an Orange micro dark and Marshall 4x12. I will post a full video on my channel unholy8155 soon, there is a pic on my instagram of the same name if you want to check that out. Cheers
