Fulltone SupaTrem (USED)

The Fulltone Supa-Trem is widely regarded as one of the finest, most musically transparent amp-style photo-cell tremolo pedals ever created. It is celebrated for its ability to deliver lush, vintage tube-amp throb without altering your guitar's core tone.

Core Tone & Waveforms

The heart of the Supa-Trem is a custom-designed photo-cell (optocoupler) that mimics the exact behavior of the tremolo circuits found in classic 1960s American amplifiers.

• Hard / Soft Switch: This toggle allows you to choose between two entirely different waveforms.

  • Soft Mode: A smooth, musical sine wave that gives you the classic, undulating pulse of an old Fender brownface or blackface amp.

  • Hard Mode: A sharp square wave that produces a dramatic, stuttering "helicopter" chop effect, perfect for modern rock textures.

Key Features & Internal Tweaks

• The Clean Boost (Mix Knob): One of the common complaints with vintage tremolo pedals is a perceived drop in volume when the effect is engaged. Fulltone solved this by designing the Mix control to double as a high-quality clean boost. Using a premium JFET op-amp, turning the mix up can actually boost your volume slightly, allowing the tremolo to cut through a dense live mix beautifully.

• Half / Full Footswitch: Instead of forcing you to bend down and adjust the Rate knob mid-song, the Supa-Trem features a dedicated Half/Full footswitch. Tapping it instantly doubles or halves the tempo of the modulation, letting you transition seamlessly from a slow, moody pulse to a rapid flutter.

• Internal Trimmer: For players who want to fine-tune the feel, there is an internal trimmer inside the pedal that allows you to adjust the shape of the waveform even further, letting you bias the photo-cell to perfectly match your personal setup.

Build Quality & Tour-Ready Reliability

True to Fulltone's reputation, the Supa-Trem is built like a tank. It features a heavy-duty, 16-gauge cold-rolled steel chassis designed to survive decades of stage wear. It utilizes top-tier components, large heavy-duty footswitches that are easy to activate with your foot, and clean, low-noise analog circuitry.
