The Supro Tremolo pedal has preamp and power amp sections with an actual output transformer that helps it re-create the saturation and coloration of tube-based effects from the ’60s. With an analog circuit design by Thomas Elliott, it emulates Class-A tube circuits using switchable Amplitude or Harmonic modes and controls for Gain, Speed, and Depth. It has an LED status indicator, rear-mounted jacks, side-mounted battery drawer, and noiseless true-bypass switching. Supro pedals are assembled in Port Jefferson, New York, using custom-tooled, anodized/brushed-aluminum enclosures. Learn more at suprousa.com.
