The only issue is when you get over 120db, your bones start to act like an inner ear and no mater how much ear protection you use the body is under stress.
So we should wear nothing less than a full face helmet with a snug fitting termination down on our chest?

Man that Bi-Polar DRSSTC is loud. We are finding that Bi-polar coils produce much better sound.
I wonder if it has something to do with two outputs 180 degrees out of phase @
I`d say it is more a question of sustaining an unbroken arc. as long as the arc is continious, the sound is extra clean. The arc breaks and makes way for ordinary streamers to air, and the sound gets --- well, abit less clean. Can`t just seem to find a word for it. So an ordinary coil arching to a grounded object is also able to *play clean*. I cannot say for sure if it is as clean as a bipolar, since I have never heard a bipolar coil, but an ordinary coil arching to ground is surely cleaner than when it is producing air streamers, and I noticed this is also the case with the bipolar on your video. Correct me if I`m wrong.
Or if you just plain disagree. Problem arises when a note is drawn on for too long, then the arc rises up in a arch, due to thermal convection, and breaks. Only to reform a new arc that is, initially, horizontal (but starts climbing untill-----) At the moment it breaks up: That sounds really awfull and must be avoided. Placing the grounded target right above the break out point seems like a good place to start. (or turn that bipolar on it`s end)

Well, I did take it to band practice. :P
My guitar signal processor is based on the work I did for Finn, so I'm still not telling how it works... If you noticed me controlling the size of the discharge with the guitar volume knob in that video, you should have figured it out already.
