That's what I used to do with a Vibrolux and a Telecaster when I played country music in Nashville in the 70s. It worked great as long as the amp was in good shape. I did used to have to carry extra speakers on the road though.
Yep. One small slip on the volume pedal and the speakers are toast and everyone grabs their ears! The Peavy Session amps solved that problem - got a balanced sound - in the 80's. Ralph was playing a Session 400 when I talked with him. I still use my Vegas 400 (a twin version because I play both pedal steel and keyboards with country bands?) for country gigs.
