This is design by John Hollis. It’s a booster that uses an inductor to generate a massive boost. It also has a switchable octave up. The boost sound is very warm and clear. The octave has a nice tone also.
There is a drop in volume between the octave and the boost, since the octave has to push the signal through a diode ring. This made it impractical to make the octave switchable with a foot switch. Hence the toggle.
I got the 3DPT toggle switches from FutureLec for a very reasonable price. I had to wait weeks for them. FutureLec is slow as mollasses, I would not recommend them if you are in a hurry.
This is Way Huge Swollen pickle clone I made. This is basically a Big Muff with using a 14 pin DIP that contains 4 transistors. The tone control also has a pronounced mid scoop compared to the original Big Muff.
I etched this design on the box. The design is based on flames in Tibetan art. I named the box the Shiva Sonic. I figure as the god of destruction and rebirth, Shiva was an appropriate deity for the sound of the Big Muff.
This is a layout for the Big Muff that would fit in a B sized box. It is set up to use a 14 pin DIP since I used a quad transistor array. The pins on this chip are arranged such that you you could use this layout with regular transistors inserted into a 14 pin DIP socket. If you look carefully you can see that I’ve marked the pins E, B and C
I just built up Jack Orman’s FET Muff. This is Big Muff built with FET’s instead of BJT’s. When I created the layout I had the idea that I would keep all of transistors in line so I could use a length of milmax header. I think this made for a better construction. It led to a more organized layout. Though it did cause a couple headaches with component placement.
This PCB board includes all of the wiring for DC jacks, Input and Output and 3PDT Stomp switch, and a perfboard area of 18 by 21. ThePCB board fits in 1590 B sized box with room for a 9V battery. Here’s a picture of the PCB with Switch and jacks. Here’s a picture of the PCB fit into 1590 B box from the bottom. Leaves just enough room for a battery.
