Vintage tremolo meets modern innovation.

Fulltone Supa-Trem Model ST-1, one of the finest amp-style Tremolo pedals on the market since its debut in 1996, just got a whole lot better. It's now also an incredible sounding clean boost!

For years people have been turning the ST-1's Mix knob down all the way, opening the pedal, and turning up its internal volume control to maximum, and using the Supa-Trem as a very subtle clean boost. Now Fulltone added a low-profile Volume knob on the outside of the pedal, and increased its available gain to around 15dB... allowing the ST-1 to pull double duty as a stellar clean boost. One reason the Supa-Trem sounds so good is that it uses a wonderful Analog Devices JFET AD711JN at the heart of its circuit, giving you a warm yet clear tone when your pedal is turned on.

The ST-1 also employs a custom-designed Fulltone Opto-1 photocell with an extremely fast recovery time which no other manufacturer can match. This makes it behave just like an old 1960's American tube-amp, but without the annoying ticking sounds that plague amps and other tremolo pedals. The Supa-Trem is the most versatile tremolo on the market, sporting True-Bypass with Blue On/Off L.E.D. and a Red Rate L.E.D. showing your speed at all times (even when pedal is Off) so you can drop right into the song at the correct tempo.

With the ST-1's large Rate and Mix knobs you can fine-tune on-the-fly with your foot. The Speed footswitch correctly halves or doubles your tempo so you stay rhythmically-correct with the tempo of the song you're playing!

Finally, there's a Hard/Soft footswitch for choosing between Soft Mode (a rollicking sine-wave) or Hard Mode, which is more of a square-wave machine-gun stutter. There's an internal trimmer to fine-tune the current reaching the Photocell to change feel of the waveform, although we recommend leaving it where we set it so you have the ability to turn down the Mix control and not hear any tremolo when using as a clean boost.

  • New Volume knob with added 15dB of gain
  • True vintage-style photocell without ticking
  • True bypass
  • LED status and speed indicators
  • Half/Full speed footswitch
  • Soft/Hard footswitch

If you like organic Tremolo tones there’s nothing that approaches the Fulltone Supa-Trem ST-1.

Tremendous tremolo pedal

By jackinvox

from Undisclosed

Comments about Fulltone ST-1 Supa-Trem Tremolo Guitar Effects Pedal:

I was looking for a pedal to use with my Matchless DC/30 that hopefully could reproduce the lush vibrato of my '69 Fender Pro Reverb, the quirky Vib/Trem of my '64 Vox AC30, and the radical tremolo of my '67 Vox Defiant. Wow! The Fulltone delivers all of that and moreeverything from the most subtle waver to the the clipped stutter featured on "How Soon Is Now?" or "Boulevard of Broken Dreams." The Supa-Trem's output is super clean and quiet and the Speed switch to automatically double or halve the rate is a nice plus. The knobs are large enough that you can accurately adjust the rate or intensity with your toe. I now find myself plugging into the Fulltone instead of using the onboard effect in my vintage amps.

The best

By John Burdick

from New Paltz, New York

Comments about Fulltone ST-1 Supa-Trem Tremolo Guitar Effects Pedal:

This pedal is the star of my pedalboard. With the adjustable internal slope pot and the eminently useful switches on top that let you double/halve the rate or select between smooth and choppy, almost square waveforms, it is easy and fast to dial in any manner of trem effect--what is so impressive about this pedal is the quality of its signal. I often use it with little to no trem dialed in just because it works like a very subtle but enriching boost pedal--tone sucker? The opposite! Thickener. The price is a little steep for a tremolo, but the thing with FullTone is robust build quality and elecronics. This pedal is lucious!
