I love my fillmore 50 combo (and the 23" matching 1x12 cab). For short moment I thought whether I should take it back within the 30 day period and upgrade to a 100 because it doesn't seem like there is as much clean headroom as a 50 watt should be. But for me the fillmore 50 seems to be perfect in most situations. I can get it right in that sweet spot for the outdoor gigs I've been doing lately. Lots of clean headroom at home. The gain tones that I use on the second channel has really ruined me for using pedal OD.
After going through several other Mesa's and boutiques I am in the same position. This is one seriously underrated amp. I am loving it. Talk about a classic rock monster. Killer pedal platform on the clean if that is your thing as well.
