There are some great guitar players who play dual-neck guitars but I have never seen anything quite as strange looking as the quadruple neck guitar. It’s the Pro Electric Quadruple Neck Instrument With Guitar, Bass, Banjo and Mandolin Necks. Apart from needing another arm with 9 or 10 fingers attached, you’ll also have to have a neck made from granite to wield this monster on stage. The ‘silver sparkly’ guitar/bass/banjo/mandolin looks like it stepped right out of one of those live 1970s rock performances and it just sold on eBay for the ridiculously low sum of around £130. Isn’t that crazy? Michael Angelo is one the player who might want to digg it!
That's pretty awesome, but it's not the first 4 necked electric guitar. Michael Angelo Batio, from the band Nitro, had a custom 4 neck made for him by Dean Guitars. In fact, he recently made made a new one. Heres the video: http://www.deanguitars.com/angelo/mab.html
Also, check google images for Michael Angel Batio, and his original 4 neck shows up.
