I was in a couple of country bands. The amp I used was the same one I used in the "blues" bands and the same amp I used to play rock from Rolling Stones to Foo Fighters, Metallica or whatever bs Ive played over the years...even dance orientated pop and disco. A fender Concert II with what ever OD pedals worked best.
Ive had it for 41yrs. It blew a fuse once, in 1999. Tube amps, so unreliable.
