We just tested out a new amp we got, an authentic vintage 1967 Fender Pro Reverb.

To test it out, we used 2 57's directly on the speakers and one AKG Perception 220 about 3 feet away, level aimed at the center of the amp. No matter what guitar we put in, whether it be a Gibson, Fender or even my 150 dollar low end Epiphone Les Paul learners guitar, the sounds I got were incredible. I felt like I was listening to a real 60s surf-rock record. Even taking away the AKG, so much natural reverb and warm sound came from that amp that it made me wonder why can't they make amps today as good as this one is?
