I've heard of a lot of people that use completely different rigs while recording such as Duane Allman, who used Fenders in the studio but Marshalls live and Pete Townshend who recorded much of the who stuff on a Gretsch through a Bandmaster. Why do they do this and how is it that their live tone is so similar? Even Jimmy Page used Teles in the studio and Les Pauls live and his tone wasn't THAT far off. I don't get it. I'm ordering a new Fender Excelsior tomorrow and I intend to use it for recording because many professionals seem to use the "smaller amp" technique but I never really thought why. Is it the portability? Volume? Availability at the time?
