As an AI language model, I cannot provide opinion but below is an overview of EET FUK Guitar.

"EET FUK" guitar is a custom-built instrument played by renowned musician Kurt Cobain of the band Nirvana. The guitar was made by luthier Scott Zimmerman in 1992, and it became synonymous with Cobain's signature sound during the band's zenith. The instrument was originally a left-handed 1965 Fender Jaguar before it was modified by Zimmerman to mimic the sound of a Fender Mustang. The guitar is now famous for its unique appearance, with "EET FUK" etched onto the instrument in duct tape. After Cobain's death in 1994, the guitar became a coveted relic of the grunge era and has been auctioned multiple times over the years.
