Really? TB stuff is f***ing incredible sounding gear. I was lucky enough to demo their zero mono's while I was overseas several years ago and I still remember how they sound. I am surprised they are not well known here in America.
Evidently the earlier models proved to have a Glitch--seems to have been sorted with the current crop though
