I'm not an electronics expert, but the 2nd pot is confusing to me. You're calling it 'gain' but there's no amplifier - it will never be louder that the output of the device you're hooking it to, right? If that's true, then aren't you really just running 2 stereo resistors in series? And if so, what's the point, why wouldn't just 1 stereo pot work? Sorry if this is a noob question! I'm asking because I just want a simple volume control, i just want to leave the unit on full volume, run a long cable to my DIY unit, and then attenuate the volume from there.Thanks,Buzz
