I'm a relative novice at electronics, I've done some guitar stripboard projects and things like that, and I'm currently making some modifications to an old synthesizer. I've done a few of the mods sucessfully, but I think the instructions I got for one of them are wrong, and I'm not sure what to do.
I was going to get into the sonic details but realized it's not necessary to answer the question. I have two separate circuits, and I want to add a parallel resistor to each, and toggle both circuits at the same time. One position would put the parallel resistor in the circuit, the other just leaves the original resistor. The instructions call for a DPDT ON-ON switch. The drawing is here, in the first post:
I did it as he suggested, it's not giving me the expected sound. When I contacted the guy who did it, he said he never actually did one like that, so he wasn't sure it was correct. Am I supposed to wire this differently than what he had indicated? I almost feel like something should go on the bottom two posts.
