LP Standard Flex-A-Tone
The LP Flex-A-Tone is a unique instrument that creates a wave of eerie, saw blade-like sounds though varied pitches.
Bend the spring steel with thumb pressure as the wooden balls strike the surface.
With a little practice, any song can be played on the LP Flex-A-Tone - we've even heard the Star Spangled Banner played on it!
The standard flexitone. Does what you need.
