In the meantime, check out some of the crazy features this thing has. It's marketed as a metal amp but its super versatile. It has nutty features like a 'Tube Safety Control' which not only protects against tube failures, but also enables you to mix 4 different kinds of power tubes and it will automatically bias it properly for each tube! He mentioned you could take out the tubes as youre playing and it would still keep on ticking, even when down to just 1 tube (though obviously at reduced power/tone).
So is that marketing speak for saying it's cathode biased?
