hey can someone help?

I wanna make this A/B channel selector, but there's some stuff i wanna know. firstly, how can I build this with a battery instead of a plug for an adapter? secondly, I live in Brisbane Australia and I want to buy a 3pdt stomp switch, without having to import it from another state.

yep, you can do that with a battery. You can see the + and - signs on the switch, apply the battery to there.

As for a stomp switch : good luck, I just import them from germany though there a couple of sites that sell them. Do a good search and you might find one in australia, otherwise...


If you can live without the LEDs a DPDT switch will also work. If you need a diagram just ask.

Wait. Just found this among my files:

with LEDs and using a DPDT switch. Not as true bypassish so I don't know if it'll suck your tone too greatly (though there probably wont be any problems if you're using this after a buffered effect: any Boss or Ibanez pedal for example). You might want to change the 100k resistors to something larger (500k maybe?).

What site did you get that diagram from? I cant remember the address

for the pixel art ones?

and just for some history: the LBP listed on there, was actually the first pedal made and sold by Electro Harmonix at the end of the 60s. Showing it off at the NAMM of 1968 (I think) they were among the first that displayed you can boost a preamp into distorting (I believe Peavey saw this and soon went on to make a tube amp with cascading gain stages in the preamp)

simon, those are similar to mine

hey thanks guys,
(seljer) in your a/b box with LED's, what voltage are the LED's?


use a resistor thats from anywhere between 1kiloohm and 10 kiloohms in series with the LED (doesn't matter if its before or after). Some of the ultrabright LEDs really don't need a lot of current (its the current that you need to limit, you can run LEDs of 220V if you get a big enough resistor) so you might as well use the larger values for more battery life (in a low power circuit like a fuzzface it can happen that the LED takes down just as much power as the circuit), as well as the fact that their ****ing bright at full power.

4.7kiloohms usuall works well enough

I use 2.2 for bright, 4.7 for medium, and 6.8 for a nice dull glow.

And yeah, just replace the jack with a battery, but I reccomend adding a jack to turn the pedal on and off. Diagrams at GGG.
