Title: A/B/C Pedal
Post by: irmcdermott on August 05, 2013, 05:21:40 PM
Anyone have a diagram for something like this (http://www.loop-master.com/product_info.php?cPath=38&products_id=50)? Where you can only choose A or B or C and no combinations? I've done some searching and have com up empty. I'll sit down tonight and try and diagram it out, just wanted to see if I could save myself some time. Thanks.

It's probably two of these in series. Output A fed into the input of the second.

Have you looked at Beavis audio?

Yeah, I agree Ian. It looks like it's just two AB switches in series, with switch 'c' choosing between the other A/B switch, and the C output.

Thanks guys. That's exactly where I was heading, just hadn't drawn it out to get my head around it.

Sorry for the crude drawing. I didn't put any grounds or LEDs in, but the signal routing is essentially this, right?

Whats the reason for those extra loops on the second 3pdt switch? are you planning to ground the inputs or something?

Other than that it looks perfect!

Yeah, so just like the Beavis layout, those loops will get grounded out.
