I think the Fillmore aint selling and they need a booster, hence the video. The 50 watt version is great i can attest to it. I want one but im leery that Mesa will release a 100 watt or a Fillmore 2.0 version this year. Thats how they roll with some of their models. Bad business imo to release the fillmore 25 out of the blue just 2 months after the release of the 50 watt version.
