What Is The Soundblox 2 OFD Guitar microModeler?


The Soundblox 2 OFD Guitar microModeler packs a comprehensive collection of new and vintage overdrive, fuzz, and distortion tones into a single stage-ready stompbox perfect for guitarists of all genres. Each effect has been meticulously crafted to provide precise and naturally responsive tones, from warm and chunky tube overdrive to over-the-top fuzz.

The Guitar OFD features incredibly natural modeling of twelve classic tones including, Marshall Amplifiers®, Mesa Boogie Amplifiers®, Ibanez Tube Screamer®, EHX Big Muff Pi®, Pro Co Rat®, Tone Bender®, Fuzz Face®, and Octavia®. The box also includes a super saturated METAL tone for the head-bangers, an extremely nasty, spitting fuzz called the GATED FUZZ, and Source Audio’s own CRUNCH TUBE, which delivers an extra aggressive tube overdrive.

The OFD is housed in a compact and extremely durable cast-aluminum casing. Its sturdy exterior and relay based buffered or true bypass switches are built to withstand endless gigging and rehearsal and the compact 4.5 x 4.5 inch footprint easily finds a place on any sized pedalboard. It also offers a multitude of forward thinking and useful design functions like preset morphing, easy-to-adjust internal noise gates, and external Hot Hand, Expression Pedal, or MIDI control — step up to an entirely new stompbox experience.
