Hey all! New to the forum and looking for thoughts. Picked these up a couple days ago. Traded a Gibson l1 Robert Johnson and a couple pedals for these three old gems. I am familiar with the old valco ('52?) And the Maggie 260 which I think is a '58? But the odd ball here is this big ole thing in black. Says "Audio Guild Corp" on the panel. Has channel called "ultraflex" ...changes output between two different speakers an 8" in the top of the cab and a 12" that's enclosed in the lower 2/3rd's. Have found a little info on the net but not much. SE were labeled panoramic...some Bonham...some versatone? Anyway... All three of these new to me amps sound awesome but this big tall black drink of water has me in awe! The sound is something else. Very deep and three dimensional...with sparkle. Plus an absolutely amazing vibrato and reverb! Never seen anything labeled "star" please enlighten me with any info you masters of old amp knowledge may know! Having a bugger of a time trying to get pics on here....how to do?
