Juction Box DIY

[Guitafuzz]

  Hello Guys Anyone who can point me in the right direction about a schematic for a juction box, the guy on keyboards in my church need one for his two keys to use the same amp, not at the same time, but only change between the two keys

Thanks in advance

It sounds like you want an A/B box.  That's what I have to use two guitars.  If this is what you are looking for just google a/b pedal schematic and you will find several.

A B box or an A B Y box

I just built one of these so I could have 3 guitars all plugged in at the same time.
I added foot switches and LED indicators.
Sorry, no pics. It's out at our rehearsal place.

I use 3 guitars all with different tunings for the stuff we play.
It's easy enough to swap guitars and unplug one, plug in the next,
but it's waaaaay easier to just grab the next guitar and hit a foot switch. 

I don't know how I got on without it before....  (stupid first world problems....)

Edit;
You don't have to make it with 4 inputs, I built mine with 3. Use any # you want.
I also did all the mods listed at the end of the article.
He says best to use 18 to 30V supply but mine works great with a standard 9V one spot.
Might be different for keys tho....

Welcome.
Just a note, I kept the gain at 1.5.
For keys you may want to set the gain at 1.
