Just a pointer to some really nice Mesa Fillmore 50 profiles on Rig Exchange. Courtesy of Robin A Weisgerber. This amp is a recent Mesa Boogie 2 channel amp going for a Fender Deluxe Reverb vibe.

The ones I have been working with are of the clean channel and one mentions a Neve 1073 mic pre. These are crystal clear and sound fantastic with single coils and mod/time FX. I see Sean Sova has done some of this amp which he mentions in the commercial page but, in the words of one famous Australian, do yourselves a favour and check out these excellent freebies on RE.
