Thunderhead was the top of the line Storm series guitar. The body
of spruce and maple was adorned with gold hardware including DeArmond
pickups and a unique phase toggle switch. The model shown below is
a 1968 model with Vibrato in the dark nutmeg finish. This was my
first ever Ovation electric guitar. The guitar has held up
wonderfully over the years and still gets frequent use. The bound
neck and diamond shaped inlays look brand new. On this particular
guitar the vibrato tailpiece has been modified into a solid tail with
out spring, even though it still looks every bit like a vibrato model.
