Cool controls such as Tap Tempo and Phase Correlation let you create a massive, stereo trem sound for your guitar or keyboard setup. Call your Sweetwater Sales Engineer and add the Supa-Trem2 Stereo Tremolo pedal to your rig today!

Fat tremolo tone, just the way you like it

To keep your tone sounding and feeling good, Fulltone loaded the Supa-Trem2 Stereo Tremolo with a pair of NOS Fairchild 2N5484 JFET amps. The volume control delivers up to 15dB of clean boost. Fulltone gave the Supa-Trem2 a mix control, so you can dial in the exact amount of tremolo that you want in your signal. If you crank it all the way to the left, it becomes a great-sounding clean boost.

Conjure the perfect trem sound with flexible controls

Fulltone's Supa-Trem2 Stereo Tremolo gives you the ability to create your own signature sound. A Waveform switch lets you choose between sine, square, and the Fulltone-exclusive Warble waveforms. Warble is a setting inspired by classic Leslie and Univibe units. Quickly dial in your speed with a large Tap Tempo button. The Phase Correlation control lets you dial in the phase between the stereo outputs. Conjure everything from vintage trem to completely original sounds with the Fulltone Supa-Trem2 Stereo Tremolo.

Who uses Fulltone?

The list of Fulltone fans reads like a who's who of guitar heroes. Both Ron Wood and Keith Richards have Fulltone gear in their touring rigs as do Nigel Tufnel from the legendary British metal band Spinal Tap and Boston badboys Joe Perry and Tom Hamilton. Punk/Rockabilly mainstay Reverend Horton Heat is a Fulltone convert. Other notable Fulltone users include Pearl Jam's Stone Gossard, Jack Bruce of Cream, perennial alt rocker Lou Reed, and Tom Petty along with Heartbreaker Mike Campbell.

Fantastic tremolo pedal

Between all the options being implemented well, running this in stereo sounds amazing. I purchased it to stave off buying a Fender amp with tremolo built in and this is so much better and more flexible.

Excellent Tremolo!

I hesitated spending the $200+ for the Fulltone Supa-Trem2 pedal for several months, but what an upgrade from my Boss Tremolo TR-2!!! The Supa-Trem2 is So quiet, (transparent) as an effect and the range of tremolo sounds I'm only beginning to explore. The mix knob is a great feature to blend the dry signal or turn the mix down to one and the volume up for a boost effect. The Fulltone power supply is also included. The stereo effects record well direct into my Delta 1010 sound card or through a stereo FX plugs on my amp or through the soundboard direct. In short, the Supa-Trem2 is an excellent value in a tremolo pedal and Sweetwater really delivered on quick shipping and followup emails. Well Done!


Top quality components and performance, as with all Fulltone pedals. Has a rich warmth most lack, but doesn't over-color, which can be a problem with some makes. For big, clean, Fender amp style tone as in country and funk I leave it on full time, adjusting the mix pot to suit. Built like a tank.

Unique Features, Lovely Sound

This pedal captures the authentic sound that you'll hear on recordings from the sixties (think Buffalo Springfield). High quality components and attention to detail, not to mention novel (and useful) features like waveform selection, tap tempo and phase correlation make this box a winner. The phase correlation knob is a wonderful touch. It expands the sound palette and makes the Supa-Trem2 a must-have. Independent LED indicators for each channel provides useful feedback when running in stereo mode. Beautiful sound for both guitar and keyboard. I ran my vintage Farfisa VIP233 transistor organ through the Supa-Trem2 and fed that into a BOSS RT-20 - superb. Can only imagine what it would sound like through the Neo Ventilator. I put a modded MIM Strat and a Gretsch 6122-12 string Country Gentleman into it...like butter. By the way, I got a chuckle out of reading the description here on the web site under *Who Uses Fulltone?*: "...Nigel Tufnel from the legendary British metal band Spinal Tap " Uhhh, guys - Nigel ain't real :) Can't wait to try this out on vocals - Crimson and clover, over and over...

Fulltone Supa-Trem2

I waited a while for this pedal to show up, but the wait was well worth it, and after a couple of gigs under my belt with this behemoth strapped on my pedal board, I've formed some opinions. So lets take a walk down review block shall we? Build Quailty 5/5 This thing is built like a brick. SOLID. All of the pots, and switches feel very nice and the housing strikes me as rugged. I've only had this for two weeks, and anytime I'm playing gigs I am transporting all of my pedals affixed to a board and in a hardshell case. This pedal seems like it will last me for many years to come! Usability 4/5 Everything is very clearly laid out and for the most part this pedal functions exactly as you would hope. Volume, Mix, Rate, Waveform selection, and even phase correlation function exactly as you would expect. Any small issue I have with this is strictly from the tap tempo control: First and foremost, if you don't know about this functionality, being able to hold down the tap tempo to toggle between fast and slow modes is a VERY NICE, almost leslie like capability, that I very much love. My only quarrel with it, is that there is no natural ramp to the change. Just an instantaneous jump to double speed or back down. Second, to get any tap tempo speeds that aren't crazy slow, you have to tap pretty darn fast. Now it's entirely possible that I'm missing some functionality here, as I have not opened up the pedal to see if there are any tweakable internal trim pots with which I can play. Otherwise, they've almost completely nailed this pedal from a usability perspective. A couple minor tweaks and I would change this category to a 5. Sound 5/5 Wow. Beautiful, tasty, and just plain old soulful. It reminds me of the tremolo on my old gibson ga-9 amplifier. Just very natural and musical. You will not be disappointed on that aspect. So that's that! A big shout out to Tom Maxwell my sales engineer for putting up with my constant check ins while we waited for Fulltone to replenish stock. Fulltone took a while to get this to you guys, but I don't hold it against anybody! 5/5 for customer service! One of my favorite things about sweetwater.
