That is super cool. I love altering effects and DIY projects. Sounds like fun!

I’ve tried building the Fuzzbox for some time, and its a real enigma trying to get it to work. I get no ‘nice, warm, fuzzy’ distorion, just a square wave. Is it [supposed] to do that?

hey, does any one know how to modify the a/b box so that 2 inputs go to 1 output. like say i have 2 guitars with the output going into the a/b box as the input and haveing one output on the box where i could switch between them.”

See my A/B box at:

lol i know this may sound dumb but i like the lay out the pic of how it is setup up the wireing digram lol do u guys think theres more sites with wiring digrams like those?

diy electronic drums, it’s a membership required site, but they’ve posted some very solid (and very free) plans for building drum trigger pads…

for more info on DIY guitar effects the best place by far to go is Aron’s DIY Stompbox forum.

http://diystompboxes.com/sboxforum/index.php

the projects on that site are pretty simplistic. if you have a look on arons forum then there’s a host of other stuff. go look at some sites in the link section. ive spent a good deal of time there and other places and the majority of my effects are either homebuilt or modified

and marnargulus, you can get true bypass with a DPDT switch, all the effects on that site are TB

Boris:
The signal of a guitar is very weak. You can’t power LED’s with it so you always add signal. A common use is the 9v because it doesn’t drain very quickly, and you can prebuild the entire power/plug/switch units before any of the main circuit. This saves time when making many boxes (boxen). You also need some type of buffer (the caps) for when you switch, otherwise you get a popping sound in the amp (you go from no signal for an instant to a signal, which is an infinately large change). When you are playing guitar live you don’t have the ability to switch an actual toggle with your hands, and it is pretty hard to do with the feet, so a stomp switch must be used. You can’t really tell whether a stomp switch is on or off by looking at it. Hence LED’s in almost all units.

The A/B box is not a signal splitter but a switch. One output gets shorted and the other is connected to the input. No splitting is going on; you just select which output gets connected to the input. This is lossless.
It’s stupid how it’s using a DC supply just for indicator LEDs. Why not use a DPDT toggle switch instead of the hard-to-find 3PDT and just use the position of the handle for indication?

Where can someone learn about circuitry online? I am a completely new to the subject.

That is a long way to go for schematic diagrams of some very basic hookups, but it shore looks pretty.

It should be noted that you can’t get a true bypass with a double pole double throw switch, so it still has to go through the circuit somehow. What you need for true bypass is a triple pole double throw (three on/off together). The exception people have built is the Millenium Bypass, which is not included in the above circuit. It would add more parts than are actual in that circuit to use that type of switch and get any good tone when you switched it off.

double pole double throw switch. Basically 2 switches that go on/off together.

I don’t know the technical name, but the 6 pin thingy is the toggle switch that you would typically step on.
