Junction box summing to mono

[therealpeterlin]

Hey guys, this is my first build and I'm looking for help on how to get this made. (I'm pretty much a noob when it comes to electronics so bear with me!)

I have a stereo rig but there are times when I'm only able to run one amp.
So I'm trying to make a junction box.

1) Mono input after drive stage -> split into 2 to go into front of 2 amps.
2) Fx sends for both amps.
3) Fx returns for both amps. (Sums to mono when only one is plugged in).

So yeah, how would I go about making this? Any ideas?

Welcome to the forum!

Sounds like you need 3 simple circuit splitters in one box.

First section: 1 in from guitar and 2 out to amp inputs
Second section: 2 in from amp fx loop sends and 1 out to effects board
Third section: 1 in from effects board and 2 out to amp fx loop returns. Just 1 out could be used if you are only using 1 amp.

You may need buffers. Some of the other guys will probably comment on that.
