ETC makes my life so simple that it hurts -- honest to goodness, it really does. I had a problem with a clutch knob and ended up fighting to get that part replaced. First the local theatrical supply store sent us the wrong part, then they sent us the right part, the knob, but it turned out it wasn't the knob that had poor threading, it was the bolt. So then I got desperate, went to the local hardware store, and bought the correct bolt, and it worked. Now, 5-6 months later, I'm in the hardware store again, and lo-and-behold, they sell not only the bolt, but the exact same threaded knob you would find on the yoke of a S4. ---- I was so discouraged and disgruntled at that point I couldn't even speak. Really. I mean, you'd think somewhere along the line there would be a special part you'd have to order specifically as a replacement, but NOOOO, ETC doesn't want to make it not simple enough, so they make it so simple that even the parts you wouldn't expect to be able to find in your hardware store, are actually there. ST, you think so hard at ETC that it actually creates more problems if owners of S4's take the time to think. You have no idea how discouraging this is. Thanks to you, I have to stop thinking. I might become as intelligent as a door jamb because you did all of the thinking for me. Here's a very sarcastically sarcastic cheers to you.
