quick question. Im satisfied with the tubes in my sebatron vmp4000e, im just curious as to how much difference in clarity, warmth, "feeling", a tube swap can do. I know the unit has 4 12AT7 tubes, but im not exactly sure what brand they are...or how high quality they are...im sure they are just fine. However, this http://www.tubedepot.com/cr-12at7.html has kind of gotten my attention. If i tried a tube swap with something like that, would there really be much of a sonic difference?..is it even worth it? Also..would at 12ax7 tube fit in the seb?
