Alvarez Yairi DY-88 acoustic guitar which belonged to Marty Friedman, the iconic lead guitarist of Megadeth from 1990 until 2000. It was used in the recording of the Megadeth songs “A Tout le Monde” and “Diadems”. Both of these songs were recorded during the Youthanasia recording sessions in 1994. “A Tout le Monde” was the second single released from that album, while “Diadems” appears on the Hidden Treasures EP. If you compare the two songs you can hear the guitar’s distinct tone, especially during the intro sections. This Alvarez acoustic guitar is also pictured on the back of Friedman’s 1994 solo record Introduction, with Friedman holding the guitar. Friedman and his guitar were also photographed together for the July 1994 issue of Guitar School Magazine.

On February 13th, 2026 Friedman brought this guitar to Rockaway Records in Los Angeles to be sold on his behalf. On that day, he provided background info on the instrument, detailed its use on at least two Megadeth studio recordings, and provided details on where to find photographs of the guitar. He then posed for photographs with the guitar, and before leaving signed the guitar on the body below bridge in silver marker pen. A letter of provenance signed and dated by Marty is included, along with Rockaway Records' Letter of Authenticity, which is our lifetime guarantee.

The guitar, which has the serial number "921487" on its headstock, is generally in excellent condition. Three small strips of white tape have been applied to the electronics system with pen markings noting which levels needed to be used while performing. There is one tiny nick on the body near the top side of the guitar. There are two small chips in the neck on the back side, and one nick on the side of the guitar. There is a small, black triangular shield that was screwed into the headstock, but has been removed (it’s included, but the three screws are missing). A moderately used Alvarez guitar case is also included.
