Hi For those who have owned or used the following amps, what did you think of them? : 1) The Engl Powerball (first generation) 2) The Peavey 5150 / 6505 3) Peavey 5150 ii / 6505+ 4) Mesa Boogie Mark IV 5) Mesa Boogie Mark V 6) Randall Satan ..... of course this isn't even produced yet ...... so don't expect any answer for this one. But these are the amps that I've come down to as far as my next guitar related purchase. What I mean specifically is : what you think of the amps tonal qualities, reliability, durability, ease of dialing in a variety tones, cleans and abilities to reproduce a few bands tones: Amon Amarth, Kreator, Metallica (Master of Puppets), Jeff Loomis, Meshuggah, Death, The Darkness, Dethklok, Led Zeppelin, The Black Dahlia Murder, Van Halen, Pantera. Also how would you rate the amps? Which do you prefer? What did you not like about any of the amps? Thank you in advance for your thoughts!
