The “see-through” Ampeg guitars of 1969-71 represented three legendary names in electric guitar history.

Ampeg pioneered electric basses with an amplification device in the end peg – hence the name Ampeg.

In 1968 Ampeg tasked musician Dan Armstrong to develop a guitar made of transparent acrylic glass. Armstrong then tasked fellow musician Bill Lawrence to not only help design one but six easily interchangable pickups, easily giving guitarists a bass or treble option.

This model’s unique look and tonal versatility (plus the onstage use by Rolling Stone’s Keith Richards) should have put the “see-through” model over the top, but they lasted only three years.

Ampeg relaunched the Dan Armstrong model in 1998 after it was used by the Foo Fighter’s Dave Grohl.
