Magical item, instrument, requires attunement by a Bard, Epic

A white, explorer style electric guitar that has been enchanted to provide amplification and effects wherever it is played, activated via a switch on the guitar’s body. If the holder is a Bard, it can be used as a focus for spells, and can also attack in its’ own right. If used as a melee weapon, the guitar deals 1d6+1.

Power Chords. This item has seven charges, and regains 1d6+1 each day at dawn. If the holder is a Bard and can play the guitar, you can strum loud chords on it, dealing 4d8 Force damage to any creatures within 60 feet of you that fail a Constitution saving throw (using your spell save DC), or half as much on a successful one. Any creatures that fail this saving throw are knocked back 15 feet. On a critical failure, fly back 25 feet and land prone.

Sweep Arpeggio. The holder can also break into solo, performing advanced guitar techniques, blasting up to six targets with a line spell generated by the magic. Six magic missile-styled projectiles shoot out from the head of the guitar, each dealing 1d6+1 Force damage. This ability can be used three times per long rest.
