I would 3xpect you could put TAD or JJ 6V6s in the Fillmore 50 (or a pair of each) and it would be fine. If it doesnt have an EL34 bias switch then get the hottest 6V6 you can find... or mod to adjustible bias.I finally pulled the trigger for a Fillmore 25 too!
After watching all the demos available online and playing with it in a store, my heart (and ears) was convinced.
But the design is a bit boring no? So I decided to make my 25-year dream come true and get a custom version made.
Issue is to have to wait until Christmas (good timing though), but I can't wait to get that premium myrtle wood with cream black grill!
Already have a LSS head + cab, but that one is clearly different. And in the combo shape/size, it's perfect for a second amp, in the living room (LSS gets the bedroom).
I really think Mesa is getting things veryvery right these days. Maybe the only thing I would have loved in the Fillmore is the multi-watt system of the Cali Tweed.
Imagine a Fillmore 4:40 with 4 6V6 (instead of the 6L6 of the 50) and the multiwatt nob.
That would be the absolute perfect amp!
