The Best thing i can do for you is comparing The Engl Fireball (wich is 60 watts) ,and the Mighty Orange Rockverb 50!
Well i play the Rockverb witha an Orange V30 cab in the rehersing Studio.
It's a Giant for Leads ,it takes pedals great ,has a usable FX loop ,and the Cleans are awesome.The Reverb is a extra cool thing when you need more cleans!
The problem is ,it's not tight.If you don't use a dist/OD/Boost pedal ,it tends to mush in mid/high gain!The sound is Marschall JCM 900 sytle ,but with more oomph and character.
The Engl Fireball is the best sounding Engl IMHO.it sounds descent in every volume ,The gain is enormous in every level.And the tonal control is suberp.
It has a ahred eq on cleans ,and cleans are not the Strength of the Engl.It's a metal machine ,and it does it better even than many other multi-channel monsters.
The sound is complex but direct ,The power is there ,and the Bottom is tight and biiiiiiiiiiiiiiig!So it's a dream amp for many lead and rythm players.Great value!It sounds big with the V30s .and sounds really organic with greenbacks!
