just another bit to add to this...
Went to take my Fireball to my mates band practice (hes buying it).
He was running a 5150 2 head through a 4x12...then when i arrived he used the ENGL...
fook me it sounded AWESOME... all the controls in the middle, mids slightly boosted... pure metal riffage!!
They play tech death\hardcore type stuff, ENGL cut through fine and sounded great. Just guitar > ENGL, no delay\reverb etc... the bottom end crunch was insane, and it cut like a knife through the noise of the drummers blast beats and the bassist.
All the band members remarked at how much better it sounded than the 5150, and how easy it was to just dial it and get 'the sound' straight off.
He used to use a Thunder, and his other guitarist uses a Mark 1 5150, they are tone heads ;)
So.. shame to see it go, but my Screamer makes up for it, and at last my Fireball gets to be REALLY cranked and make some ears bleed 8)
