I'm thinking of building this A/B Box for my pedal board to make it true bypass (apparently), and I understand how to build it.. but I don't get how it would work. I see an input jack, and two others (FX In and FX out, I assume).

Where would the connection go from there, without an output jack to the amp?


Also, when I look at the diagram, I see resistors there, but on the downloadable part list (http://smallbox.zeonhost.com/projects/abbox/abbox.txt) they're not listed.. do I need em?

It's a signal switching box.

Click the switch directs the output to either 'Out 1' or 'Out 2'.

You'd use it for switching between two amps.

Edit: Or have your pedals connected from 'Out 1' to your amp, and have 'Out 2' directly to your amp (both wired to ONE mono plug). You'd have volume-levelling issues though.

Edit2: Yes, you do need the resistors.

well now I feel like an idiot!

I've found another kind of box that DOES create effects loops for pedals, but thanks!

Have a look at this thread for info on making a true bypass block:

Here's the diagram I made for the other guy:



Edit: If you just want to bypass your pedal chain, use one section of that ^

Also, make yourself an LPB to match the bypassed volume to the effects loop volume.

Dude, you're brilliant, that's exactly what I need!
Thanks a lot!

Edit: I'm also kinda new to the whole soldering thing.. where do all the grounds go? (lol)

The easiest thing to do is to just solder them to the enclosure.

Oh, and also, where would the LPB go? I have the diagram to build one, just not sure where to hook it up. Does it go after the bypass box, or is it part of the effects chain?

I'll make another diagram that might suit you better..
