OGRE is a South Korean musical instrument brand known for its visually striking guitar effects pedals. The core pedal lineup — Tubeholic Overdrive, Thunderclap Distortion, Kronomaster Delay, and Fuzz Lion — are housed in die-cast aluminum enclosures sculpted into the forms of menacing demon and alien heads, finished in four anodized colors (gray, red, green, and yellow) with glowing LED eyes that illuminate when the pedal is active. A signature engineering detail is a sliding cockpit-style cover that protects tone settings during live performance. The Thunderclap Distortion's four horns double as its control knobs, while the Kronomaster and Tubeholic models feature retractable frontal lobes that flip open to expose their controls.

Beyond the original quartet, OGRE expanded into a Pro Series offering a wider range of effects including the Full Tilt Boost, MOSTERT Drive, Tremoloid, SQUASH Comp, Flexroom Reverb, Fuzz Buster RT, Cosmica Phaser, and updated second-generation versions of the Tubeholic Overdrive and Kronomaster Delay, as well as dedicated bass variants. The brand also produces electric guitars under the Magnox and Transwing series, notable for being built from magnesium alloy rather than wood — a material OGRE claims produces longer sustain and a brighter, more transparent tone.

OGRE debuted its pedals at international trade shows including NAMM and Musikmesse, with MMG Distribution handling North American distribution. The brand markets its products to both touring and studio musicians, emphasizing ergonomic design alongside unconventional aesthetics.
