How to make these?

[DonB]

Anyone have any idea how to make one of these types of loop pedals?

I would also like to add a tuner bypass.

I need the channel select function with the loops.

For the change channels option you only need to know how it is wired in your amp and add it to this circuit. The question now can be that you has to use relays to do all that work because probably can be so difficult to find switches with all the connections that you need for that. IHMO.

Don't take this the wrong way but if this pedal does exactly what you want , then i would recommend to buy one then copy it and then sell on the original, it's cheap enough anyway.

Yeah the pedal does some of what i want, but not alot.

The  other part i need it to do is have a dual loop for the effects loop. then i can have my lead sound on one loop, my clean sound on another loop and also have the channel select with an OD on its loop.

erm idont get what you want exactly but i guess it's doable with a 4pdt switches which aren't rare artifacts anymore
