_tom_, ummmmmmmmm, NO :twisted:
As for which to use. Well, after very little time thus far I would have to say (cough,choke) the Mesa is alot easier to get 'nice' tones from. The definition is tremendous and the different modes (clean-raw/pushed, dirty-vintage/modern) make wonderful sounds easy. Have to say a seperate EQ for channels helps (thus ENGL gets abit of a by there).
Just need my explorer back (or get BKP's in the Pet) to put a 'real' pup through it for better clarrification.
Also depends on workout. Feeling tired then move the ENGL, feel like a workout, move the Mesa (omg the thing is HEAVY!).
