Well, no steam punk...yet. Been using this setup nightly and love it, I can fine tune to my OCD's content all the while being lazy and not moving from my listening spot. Only change I made was for a slightly heavier string, the white one was fraying from the knurled knob on the CSP.
Today the remote units arrived. While unpacking them it hit me, what if the remote codes or frequencies are the same?!?!? Yep, they're the same. I hooked up one unit and either of the remotes can control the volume. There's nothing on the board or inside the remote to switch the frequency like garage door openers. Oh well, I'll at least proceed with making one.
