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 is treble booster from the Stompboxology. This was an interesting new letter published by Nicolas Boscorelli. Who has, it seems, disappeared. If anyone has any information about this guy please email me! I looking for issues of Stompboxology. I have a few I can trade. There are some posted at http://moosapotamus.net/.
He also published The Stombox Cookbook. Which is very cool. It contains a lot of original and interesting Stompbox designs.
It has an interesting and original design based around a pair of FET’s.
Here’s the schematic that I redrew from the Stomboxology article.
This is an Ugly Face by Tim Escobedo. I think the sound is pretty good. It makes a sort of pulse width modulated square wave via the guitar signal driving a 555. Not for every occasion. But the sound it makes it makes well. I really like this thing, so much in fact that I’ve made 3 so far.
Here’s a layout that would fit in a B sized box.
Here’s a modification of Tim’s original scheme that adds a blend knob. The blend knob mixes between the signal coming out of the 386 and the signal coming out of the 555. This adds an extra knob to the build, which makes for a pretty tight arrangement. The 16mm pots would work. But, 12mm pots with 1/2″ knobs would work well. Something like this at Mouser.com These pots are the same as the typical pots but they have a 12mm diameter body. A 1/2″ knob is about the same diameter.
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.
