The Vox Ultrasonic incorporated classic Vox effects into an acoustic-electric guitar, including distortion, treble boost, bass boost, wah-wah and more. This short-lived guitar was made in 6 and 12-string models from 1967-68 and came in Sunburst or Cherry finishes.

This Sunburst model resides in the UK with Jules Haffegee, who has made sound clips of the guitar available
