With the popularity of surf bands – especially The Ventures – taking hold in the late 1960’s, Mosrite guitars started gaining traction. Soon there were many knockoffs coming from Japan, these two with the Silvertone brand. It was a simple, solid body design, with the Mosrite body shape and featuring the slanted pickup mount. But this one had three pickups with individual on/off switches, making it 50% better than the Mosrite. Not! Bolt-on neck with zero fret, truss rod access in the heel and a crazy long tremolo arm. All in all a pretty good budget version of the real deal with great tone. This model also came in 2 pickup versions, another version with slider volume and tone knobs, and for some reason different headstock shapes were available. I am not 100%, but I think this was due to different import companies. So for example, Sears in USA had a different headstock than Sears in Canada. You can also find the identical guitar with alternate branding, such as Kawai.
