This is a 2x12 combo. The JTM C212 2x12 extension cabinet is a perfect compliment to the JTM 622. Note 2: The JTMs are now shipping, at least in the U.S., with 5881 output tubes. The 5881 has a sound that many guitarists prefer ... it doesn't distort as soon as the EL34. It may be an appropriate replacement in a combo amp. But if you want that classic, Marshall smoky growl, you may want your dealer to re-tube your amp to EL34's. (Don't forget to have your amp re-biased if you go for an output tube swap!)
