Did someone post a link to a simple A/B/Y box a little while ago?

I thought I saw it here, but I could be wrong. I thought I saved it, but I can't find it. For all the thinking I'm doing, I'm not getting very far.  ???

Here's a diagram for an A/B or A/B/Y box...

The second one seems to be a waste of money since it uses 3PDT switches when the top one only requires DPDT switches.

"I think" it was a link to a parts supplier who had an A/B/Y diagram as well as Fulltone's A/B diagram in his site. I should have made sure I bookmarked it. Doh!

These days the 3PDT are cheaper than the DPDT's.

I get my DPDT switches for $2 and change. All the 3PDT's I've seen are about double that.

This isn't an A/B/Y box, but just in case someone is looking for an easy to build A/B box....

Mine is a redraw including LEDs of a schem often posted by Andi.  It grounds the unused channel for low noise, which one with DPDTs does not do.  If you are using this for switching between two amps it is essential to ground the unused amp input.  Just think of the noise you get from having a guitar cable wafting in the air.

What you need depends on what you are doing. Do you only need A/B and no Y ? What signals are you switching ? You may need an active A/B/Y. You may need isolated outputs.

There is a lack of information as to what the OP needs are so a recommendation is hard to make. Its all guess work at this point.
