Tools, Tones and Toys for Guitarists
First version with external switches. the design itself is completely different from later versions with two cascaded Szisklai silicon / germaium pair transistor stages. Switches A and B adjust gain and Switch C adjust bias of the second transistor pair. The original had Dale resistors which explains the odd values but use closest common values. … Read more
This was a request. It is basically a stripped down Big Muff without external gain control, tone control and recovery stage. Decoupling caps is a bit bigger than most Big Muff variants and the clipping diodes is LEDs and Zener diodes.
This is an obscure octave down fuzz from Italy, manufactued in 70’s. The three pontentiometers adjust normal fuzz, one octave down and two octave down. Note that I made small mod to this one since the original SAJ110 IC is long gone obsolete and expensive. It is replaced with a CD4024 binary counter and divider … Read more
I used Kit Rae schematics, but I did not follow the same component numbering, as I don’t find it all that intuitive. Kit did it that way for a good reason, this way works better for my brain. There’s also this excellent post by Kit Rae on the EHX forum, broadly describing differences between versions. … Read more
A J-FET / MOSFET amp emulator of Krank Krankenstein. Very interesing transistor setup with MOSFET and silicon diodes in some of the gain stages. Schematic specifies KP303s for the J FETS but western analouges is J201 and 2N5457/58. Managed to keep it reasonable small so the brave one could try to fit this 6 knobber … Read more
MTK has played around with some one knob fuzzes and expanded it to a 4-knob domm/sludge machine. Product description ;-): S.M.F.R. Fuzz The Stony Meat Face Ritual Fuzz combines the best parts of three of my favorite pedals. The grindy bite of the DAM Meathead, the raw low-end of the BAT Ritual Fuzz, and the … Read more
As far as I know, only a handful of D*A*M FZ-678 were ever made, maybe 5 in total – it’s a variation on a Zonk Machine. It’s the same structure as a Zonk / MKI, but with a filter attached to the input. I haven’t made a layout for it, as it’s all there to … Read more
Since I’m on a bit of a tag board thing at the moment, I thought I would copy the Ghost Effects Warmjet V layout from a couple of photos – why I don’t know, as I already have a point to point version that I’ve built. Anyway, here it is… I’ve been looking at this for … Read more
