After using a Jensen C12N speaker in my old Blonde Fender Deluxe, that I no longer own (some of us have to pay the rent). I recommend it but only if you like vintage tone, now it's a lot different again to the sound of the Celestion Greenbacks, (it's the best greenback speaker by a mile) in fact it had a very agressive growl like mid range tone to it and it's very very warm and dynamic. I called it the 'growler'. Unfortunatley never got to play it with my new Mule and BKP90 pickups, maybe then I would've kept the amp. I do prefer the sound of Greenbacks compred to the Celestion Blue, they are smoother, warmer, not as trebly and work well with humbuckers! The blue's are more suited to bluesy, rich, cutting tones, and the green more for jazz, rock and soul.
