Combo Pedals - Do I just chain the output to the input of the second one?

[airbud]

Hi all, I have a couple combo build ideas, but my first is pretty straightforward: op amp and transistors big muffs, with two footswitches and a toggle to flip the order.

My intuition tells me I can just wire up the inputs and outputs to the order switch utility PCB and call it a day, but before I go nuts doing anything I wanted to make sure I knew how to do this "properly."

It seems like doing this might "waste" components in that there may be some duplication of buffer and power supply-related circuitry. Or does all input/output impedance matching still apply as if they were separate pedals?

Thanks!

Oh, and I'm calling it the "Double Stuff."

The wiki may have some answers for you but maybe you've seen that already.

I saved this image of someone's build when I first started to help me with the break out boards.

You could just use a switch without any pcb


You mentioned „waste“ so skip the pcb.
They are still seperate pedals just with another switch in between.
I wouldn’t worry about waste of components as long as you there are no redundant pots or expensive transistors.

exactly the information I needed!!! the pic is extremely helpful, I'll be saving that as well as the switching diagram.

I had already bought a couple of PCBs but moving forward I'll go with this method.

Thanks guys, I really appreciate it!
