I've been doing mods via this site (and the original Guitar Nuts forum) for a few years now. Basically when I started I knew nothing about electronics. Don't know what a resistor or a DPDT switch was, and I still can't read a schematic properly.
Every mod I've done has required some pretty basic intructions, ie: "solder this wire to this point" etc.
Recently I want to do a mod to my ABY box. It has one in that goes to two switchable outs. It also has an Aux in/out, which didn't appear to be much use for anything. I wanted to mod it so that I could split the channels and utilize the Aux as an in for the second channel, giving me two sperate switchable in/out channels. This was so I could run the left and right signals from my stereo delay into two amps, while still having the ability to mute either or both amps. Ashcatlt showed me that all I need to do was remove one wire, so that was great, all sorted.
Recently I realised that it there were some benefits to having it the old way. I have a BBE Sonic Stomp pedal that runs after my delay which gives extra clarity and sparkle to my tone. I do prefer to have it after the delay, but it meant that if I'm running two amps with my modded ABY, that one amp was missing out on the BBE. Not a major drama, but I thought it would be nice to be able to switch between modded and unmodded.
I thought I could probably figure this out for myself, so i bought a little SPDT toggle switch (a year ago I wouldn't have even known what that was) and wired up the removed wire to be switchable. There was an unused hole in the chassis where there used to be a battery check LED, which had slipped out. I use an adaptor with this anyway, so I don't need the LED. I used that hole for the switch.
One problem though. I found that because I had a signal plugged into the Aux in/out, that when I use channel 'A' the tone wasn't right. I guess the two signals were clashing, and it was giving me a slight 'out of phase' sound or something. 'If only I could rig it so that the Aux input was disconnected at the same time as the channels were linked' I thought. (Didn't want to have to unplug the Aux jack all the time).
I thought I'd have to buy a DPDT switch, or a second toggle. But after studying the original wiring I realised I could do it with what I had. And it worked! This is basically what I did:
...and here's the finished product:
So I realise this is the most basic mod in the history of mods. And I realise most of you guys will be going 'well woop-de-do-dah'. But I'm stoked that I managed to figure this out myself without needing any help. It shows that I'm finally starting to understand some of this stuff. But only thanks to the help you guys have given me over the years. Onwards and upwards from here.
Only problem is, I still get the ground loop hum when I hook up both amps, so if anybody knows a simple ground lift circuit I could slip in there that'd be awesome!
