How to switch trannies in a pedal?what kinda swith do I need

[samzeppelin]

I want to be able to switch transistors in my fuzzface
and i wonder how? wich switch shall I use?
how would the circuit look like?

Ok, just to make sure... What is the word "trannie" used for most often? Transistors or transformers? I thought they were transformers...

In a bit of confusion...

transistors i think/learned/read/saw/heard

usually transistor, sometimes transformer but that's usually abbreviated Xformer.
switching trannies? Youre in for big BOOMs with that!
But any 3PDT should be up to it. Per tranny that is....
Sockets are a better idea, probably!

[JimRayden]

You can put the tranny sockets on the top of the pedal and surround it with a wire cage... you know like on those tube pedals. Ok, ok, kidding.


I think the best way would be to mount 3-legged DIN or XLR connections on the pedal. Then buy a few of DIN or XLR plugs and fit different transistors inside them. Then you have "building blocks" you can very easily remove and replace, even on stage. And you could disguise the XLR connectors to look as tubes. Lots of cool ideas if to think of it...

I think I'm gonna try that one out on my next transistor pedal.

In this forum, trannie is usually a transistor.  On the amp building forums I've been to, it tends to be a transformer they're talking about.

I asked that question a while back. It can be done with a DPDT switch. Here's the thread:

looks like khas evets and mike was the only ones who got the Question
thanks for the replies

I now officially hate you for disregarding my idea. I shall put a curse of The Great Hum on you. All of your next pedals will hum like hell and you will be forced to buy cheap mass produced pedals that will hum too.

:twisted:

Ok, let's sit back and enjoy the curse take effect. Meanwhile I'll be playing through my module-changing boxes. MUHAhahaa *cough*

Ok, ok...

I have been toying with the idea of using a 4pdt switch... available at mouser for like 4 bucks i think.   As mentioned before... use 2 poles to switch the collectors and bases (leaving the emitters connected)  then use the other 2 poles to re-bias the transistors.
