ABC Schematic

[Fog]

Hi!

I've searched the forum and googled after some ABC box schematics, but i can't find anyone. I've also posted a topic in the schematic section of the forum with no replies so far.
Can anyone help me?

Thanks!

Can you define what an ABC box is? I've seen the Kendrick one and here's the question, what are the outputs going to?

Here's what it sounds like:

Guitar->BOX-> 3 outputs with or without switches to mute/unmute the output.

It CAN be that simple, but you may encounter ground loops.
Then it can be:

Guitar->op amp circuit for minimal isolation-> 3 outputs with or without switches to mute/unmute the output.

Or even:

Guitar->op amp circuit->isolation transformer-> 3 outputs with or without switches to mute/unmute the output.

Here are links to help you:

Doesn't that Morley one have a great chance at ground loops?
