Is anyone in here using the Fender Pro Cabs? I read alot about Ampeg, Aguilar, Bergatino and Mesa but I have yet to read about anyone using the Fender Pro cabinets. The 8 X 10 and their 4 X 10 cabs look nice in the catalogues but have not seen any in a store and have never seen / heard anyone play them live. Same goes for the heads. I have seen a few but havent heard any. Any comments on them?
