Whether you want subtle shimmer behind clean chords, classic Fender-style throb, hard percussive chops, or something a little stranger, the original Catalinbread Semaphore delivers it with character, clarity, and zero fuss. Simple, powerful, and purely musical—this is the tremolo that still holds its own years later.

Works perfectly and sounds good. Original box is included.
