Housed in a beautiful powder coated Blue 16ga. steel enclosure, the dual-channel Full-Drive 2 Mosfet gives you the best of both worlds. The first channel is the Overdrive Mode, capable of clean boost or non-compressed overdrive or choose light to medium softer overdrives all while retaining your guitar's original tone. The Tone knob is a very effective presence control that can smooth out or add upper harmonics. The second channel is the "Boost Mode" with its own separate distortion control for medium to higher gains with a more singing violin-like sustain!

One mini-toggle lets you choose between a "Vintage" FD2 sound with mid-heavy tones that cut through the mix and "FM (flat-mids)" for a more natural, transparent sound that works awesome with a Strat's neck pickup.
The other mini-toggle lets you choose between Mosfet and Normal clipping modes. Normal mode is even more asymmetrical, sweeter and more open, with no "blanket" over the sound.

Full-Drive 2 Mosfet

The Fulltone Supa Trem 1 Tremolo Pedal provides you with an organic-sounding and amp-like tremolo effect with an authentic photocell and LED circuit. It features large controls that allow for adjustments by foot on-the-fly, including a half-speed tempo switch for perfect song speed matching. The Supa Trem gives you the option of using a hard square-wave or soft sine-wave tremolo sound, alongside the ability to control the amount of effect in your overall mix. The high quality Analog Devices JFET circuit means that the Supa Trem also makes a wonderful clean preamp for your guitar, whether or not you choose to utilise the tremolo effect; Fulltone have included a clean boost volume control for this very purpose. The Supa Trem gives you incredibly organic tremolo sounds, generated with a true optical circuit to deliver versatile tremolo sounds alongside a clear and warm, general purpose clean-boost/tone-enhancer.

The Fulltone Fat-boost V1 is a discrete FET clean boost pedal known for adding warmth, fullness, and a slight midrange bump to your guitar tone without significantly altering its character.

Fat-boost V1

The OCD pedal is the only pedal that uses 2 x Mosfets configured as hard-clipping to 'Voltage reference" instead of the usual way: to ground." The earliest OCDs used 2 x Mosfets plus 1 x Germanium diode, but very quickly these diodes became harder and harder to find, and they became expensive.

Recently I stumbled across a reasonably large stash of the right kind of Germanium diodes so I ponied-up and bought all of them. So I decided to do a run of the ultimate OCD: a Custom Shop offering with a few circuit tweaks using 2 x Mosfets plus 2 x Germanium diodes, and one hell of a beautiful paint job... Metallic Teal with a chrome undercoat! This beauty morphs between blues and greens depending on the light and angle. And what would the ultimate OCD be without a Blue LED? The sound? Great definition, more tube-like feel, a bit wider dynamic range, more sustain, and a more focused single-note tone. And as with all Fulltone pedals... 100% Built in the USA.
