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.

Catalinbread Karma Suture

Catalinbread has released two versions of the Karma Suture, one germanium and one silicon based. Both at their hearts are simply a modified Harmonic Percolator. I think Catalinbread described it best on their site:

A bubbling cauldron of even-order harmonics!

The only change I made in the layout from the schematic is I added a 100uF cap from power to ground to assist in power filtering. Schematic can be found here. Enjoy my fellow fuzzheads.

FAL Treble Boosters

 Found these posted by the one and only pinkjimiphoton on the usual places. Both are very old and rare always on fixed treble boosters. Should be quick fun small builds. You can easily make them NPN by flipping the electrolytic caps, power and ground connections. I believe low gain transistors will work fine in them.

Monster Effects Mastortion

I know, I know, it's been a long time since a new layout has been posted. We have not gone away, just time has a habit of getting away from you, especially with the current state of the pandemic. I've got a running list for more layouts to come, but I don't want to post them all too quickly. I hope everyone is staying safe and healthy.

I want to start the year out with a new layout. This is one I've had waiting in the wings for awhile and finally had time to site and make a layout for it, so without further adieu. 

 The Monster Effects Mastortion was originally a limited edition pedal designed with Brent Hinds of Mastodon as a heavy OD/Distortion that's on the verge of fuzz. Not much info on it, as it was originally made in very low numbers. It's basically YATS with a set tonestack. The only changes I made was to the power section as the original has an interesting setup with bridge rectifiers and I don't feel it's necessary or adds anything to the pedal. Schematic can be found here.
