Title: Does anyone know of any A/B/Y projects or builds?
Post by: rfdvrcasey on September 05, 2022, 03:46:17 PM
I'd like to build some sort of switching pedal so that I can do some pedal shootouts with all of the various pedals I've built over the years.  I've found 2 different schematics on Google but they only partially function.  I'd appreciate any suggestions, thanks!

Here's one I use often for A/B pedal comparisons.  One guitar in, one amp out, two loops for pedal shootouts.  Either loop A or B is active.  No LED but you don't need one with a toggle switch, the handle points toward the active loop (A or B.)  Just requires a 1590B, a 3PDT toggle and six T/S jacks.  (This toggle is a 4PDT that I had on hand.)  I was going to etch the enclosure but got lazy and left the Dymo labels.  I don't have a schematic but all the wiring is color coded (brown = shields, white = in, yellow = out, others are the loops.)  The Send of the inactive loop is grounded to prevent oscillation in high-gain pedals.

Thank you! This looks like exactly what I was looking for.
