Hi Guys! I'm using an Egnater straight-front 4x12 with Celestion Greenback speakers (i.e., the Chinese-made G12M). What kinds of tonal changes could I expect to hear if I swapped them out for the Heritage Series greenback? I think that the Heritage series GB is made in England, but I'm not sure if there are any other differences aside from that? I'm just wondering if this change would improve my already great tone (using a Blankenship Custom 45). Thanks!
