Although I am fan Of Mesa Boogie, I could never find my tones in the Lonestar that I find so easy to get with the Fillmore.
In this comparison I prefer the Cali Tweed. But although I like the tone of the Cali Tweed, I need two channels, as I'm plugging straight in on stage. And I need to get a good rhythm tone with the ability to switch to a good lead tone without pedals. That's why I love the Fillmore. The two identical channels make it easy to dial in a great lead tone that works with the rhythm tone. In the past all the mesa amps that I've used were voiced to middy on the lead channel. And I like the bigger 6L6 tone over the 6V6 tone. Which is funny because most of my amps are 6V6.
My favorite tone in this video is the ES335 with a bit of reverb.
