Curious what speakers they are using for full range? I'm not as particular about the tweeter, but the 12" speaker (s).   I know on my Spider IV they are custom Celestions, and I am hoping these new amps are the same. I have always felt that part of the tone comes from using actual guitar speakers. I realize using PA speakers might offer more flexibility for the instruments the S5 can take, but I worry about that "disconnect" feeling a PA speaker might give when playing a guitar.   Ultimat
