If you’re putting a dual pedal together I’d highly recommend picking up an order switch from PedalPCB. Unless you’re absolutely sure you’ll always want one pedal pushing the other, installing an order switch gives you a completely new dynamic to the dual pedal allowing you to change which pedal pushes the other. You can get a 3pdt toggle switch or just another footswitch and with a simple flick of a switch you can (sometimes completely) change the sound and feel of the dual effect. I recently made a dual Greer Southland/EQD Black Ash with an order switch and it hasn’t left my board for quite some time now. It’s a ton of fun!
