The super producer, Marvelous 3 leader, and newest member of Train details his single-channel slugger, which uses both EL84 (cathode bias ) and 6L6 (fixed bias) tubes that can be engaged separately or together. A six-position input gain selector revamps the front end of the amp, changing feel and response rather than just adding gain.The amp is paired with a Divided by 13 2x12F cabinet, loaded with the new Divided by 13 454 speaker, a 40-watt Celestion Greenback built in Celestion’s UK factory.
