Hey everybody!
I'm building a demeter tremulator clone, and I would like to add a LEVEL control of the tremolo, but i don 't understand where to add it, how can i do that?
I'm pretty sure you can do what's done on most effects, and make it an attenuator. Connect the output from the board to lug 3 of a 100k pot, connect lug 1 of the volume pot to ground, and lug 2 becomes your new output.
The output from the first effect would become the input of the second. Look at the off board wiring section if the site, there's a diagram showing how to wire 2 effects in one box, as well as adding a switchable boost. Here's the one for 2 effects:
