Recently, I had the opportunity to play with a loaner Marshall 1x12 for several weeks, which I "converted" into an extension cabinet for my F-30 1x12. It was really the first time I ever played through more than one speaker, and the fullness of the sound was great! I enjoyed it so much that I am thinking of picking up an extension cabinet but don't know if I should get a 1x12 or a 2x12.
So I'd like to hear from the voices of experience. Will I be giving up anything by not getting a 1x12 and by instead going with a 2x12?
