The guitar Mike plays is supposed to be Kurt Cobain's 1959 Martin D-18E acoustic guitar, famously played during Nirvana's MTV Unplugged performance. The guitar sold at auction in June of 2020 for over $6,000,000 (a record price for an auctioned guitar) to Australian businessman and owner of RØDE Microphones, Peter Freedman. At the time of the auction it was owned by ex-husband of Frances Bean Cobain, Isiah Silva, who received it as part of their divorce settlement.
