Hi there, I just found an old combo. http://www.e-bass.net/bass/guyatone1.JPG http://www.e-bass.net/bass/guyatone2.JPG http://www.e-bass.net/bass/guyatone3.JPG http://www.e-bass.net/bass/guyatone4.JPG http://www.e-bass.net/bass/guyatone5.JPG http://www.e-bass.net/bass/guyatone6.JPG http://www.e-bass.net/bass/Guyatone7.JPG http://www.e-bass.net/bass/Guyatone8.JPG I dont know much about it. It has a PCF Pull/Push Knob, an "emphasis" knob and a 3-Band EQ. Power must be around 50 Watts. It has a 15" Speaker. So far I found out that Guyatone build amps in the 60ties and 70ties. This thing is either from the 80ties or the 70ties from what I see inside. I also do know that it is a 'beginner' amp, but it has some interesting sounds - I like it Any information about it?
