I'm playing a 1967 Fender Bassman through two different cabinets:
1971 Marshall 4x12 1960A vs 1965 Fender 2x12 Bassman. Both cabs are stock. The Marshall has Celestion G12M25 75Hz Greenbacks (Pulsonic) and the Fender has Oxford 12T6-1 speakers. I'm using both Gibson Les Paul and Fender Stratocaster
