MOJO
Fender Blender MOJO layout
It is all about the MOJO! Got a comission to build a bunch of the larger classic fuzz circuits using “mojo” parts, more preciely 1/2w carbon composition resistors and axial electrolyctics/tantalums. It may not be a huge difference soundwise but it is quite fun to build and it looks cool.:-p. Power filter caps remains radial … Read more
Monolith Oracle Fuzz
A simple but heavy germanium fuzz using PNP transistors with normal power supply. What not to like? The original used fairly high gain OC76 cans but others with less gain will work as well. Just keep the leakage reasonable low when selecting the transistors. Two layout for this, one normal compact and one MOJO with … Read more
Electro Harmonix V2 Big Muff Ram’s Head “White Can version” 1974
It is Pie Day so here is a layout of an old Ram’s Head variant. Rarely cloned and some cap values is not found in any of the other vintage EHX variants. 220pF/680pF caps replaces the standard 470pF/500pF values and the tonestack has less mid scoop. Still added a Mid switch for some sligtly boosted … Read more
Dunwich Amplification Hybrid Cthulhu – 3 knob version
Another Dunwich trace by evilarsen, AlexS and fuzzhead. I believe this one was made on custom order and/or was a on/off product. However, compoent values varied over time but we added some notes at the bottom of the layout and schematic for the most significant changes that is worth experimenting with: Input capacitors connecting to … Read more
Electro Harmonix V1 Triangle Big Muff 66#5 – 1969 perfboard version
Can’t believe I haven’t posted this one yet since it is one of the better vintage big muffs I built and played. In the very early days EH, component values varied quite a lot so this layout is based on Kitraes schematic HERE. There is also some notes and info the component values. Trannsistors is … Read more
Electro Harmonix V1 Triangle Big Muff 66#11 1971 “Green Cap”
One of the more common of all the Triangle variants, easily identified by large green film caps which usually was 120nF or 100nF. Compact layout And a “mojo” layout in the vein of vintage units with 0,5w carbon composition resistors. The brave one could fit it in a 1250b enclosure.
