Russell made the video because, at some point, he bought a used Strat at his local guitar shop and soon realized it was fake.
Well, this sort of thing seems to happen to Russell fairly often, because that's also the back-story to his follow-up video, "How to Spot a Fake Gibson in Seconds," which you can stream below.
"I picked up a fake Gibson Les Paul Custom Goldtop at my local pawn shop." Russell writes. "Within a few seconds of playing, I realized it was a fake, and a bad fake at that. In this video, I compare this fake Gibson Les Paul Custom to an Epiphone Les Paul Custom and a Real Gibson Les Paul. Here are the things I identified as fake: poor binding, the truss-rod cover, the fret inlays, the bridge, the serial number, the headstock, logo, tuners and more."
Basically, if you have doubts about a recent purchase—or if you just want to be prepared for the future—tou might find some valuable information here.
