Who says you can't teach an old console new tricks? It's never not cool when some inspired person takes a now-defunct video game console and turns it into something else, be it a handheld device or something else entirely. Take the Echo Canyon Guitar Company in Decatur, Georgia, for instance.
They created and sell a six-string electric guitar built from a Nintendo Entertainment System, the 8-bit console that pretty much launched the Nintendo brand in the United States during the mid-1980s. Echo Canyon dubbed their awesome and Frankenstein-y creation the "Guitendo," which was purchased by YouTuber Rob Scallon, whose channel mainly consists of him playing guitar music.
Don't worry, Scallon isn't the only person alive with access to the guitar. Echo Canyon Guitar Co. sells them to the public for $449 a pop (plus $45 shipping). You can pick one up here. For an additional fee, you can add a different color, external/internal lighting, and custom artwork. The good news is that it can be oriented for right-handed players or left-handed players at no additional charge.
But it doesn't stop there, because they're also open to using other consoles (SNES, Famicom, PlayStation, Sega, or other) to build you the baritone or bass instrument of your choosing. The prices for these custom orders must, obviously, be negotiated between the customer and manufacturer and are, therefore, not fixed.
