The Vintage Octa Screamer is not for the faint at heart! It recreates the famous and instantly recognizable octave doubling effect immortalized by Jimi Hendrix. The Vintage OctaScreamer is based on a unique new circuit design that greatly improves tracking and doesn’t kill sustain and overtones like other octavia pedals are prone to do. It also includes innovative new features refining an already legendary effect.
