“Is this the best guitar I've ever played? Including the ones in your museum? I believe so”: Opeth's Mikael Åkerfeldt teams up with Martin to create a new signature acoustic that blends traditional style with a key, ultra-modern twist

Mikael Åkerfeldt plays his new signature Martin acoustic guitar, with lush greenery behind him.

Last year, Swedish metal guitar hero Mikael Åkerfeldt – along with his Opeth bandmate, Fredrik Åkesson – visited the Martin Museum in Nazareth, Pennsylvania.

Much to their delight – Åkerfeldt went so far as to call the museum “the Holy Land” – the two guitarists were given free rein to take even the museum's most valuable acoustic guitars for a spin.
