The HI MODE of the Fillmore line offers up some hefty crunch and low end punch when opened up through a closed back cab. The 2x12 Fillmore open-back extension cab is a great match for the Fillmore’s clean and medium gain tones while offering some gritty midrange cut for higher gain sounds. Closed-back cabs like the Recto Traditional 412 Straight definitely fill out the bass and deliver some boom. #Fillmore50 | Mesa Boogie
