Back in the late 1960s—Jimi notwithstanding—the cat’s pajamas of amplifiers were solid-state. Tube amps were heavy and prone to feedback. Solid-state amps were clean, big, and loud. I ran a whole band off a humongous 350-watt Mosrite amp. The mix sucked, but we were loud! The most desirable amps at that time were made by Standel and, to a lesser extent, Kustom (depended on your kind of music). It was only later that I learned that both companies also made guitars, like this ca. 1966 Standel Model 101 Custom Deluxe Solid Body Guitar. Heavy!
