Omega Ampworks is a US-based manufacturer of high-gain tube amplifiers, custom speaker cabinets, and related accessories. Founded in 2010, the company began by building speaker enclosures in Cincinnati, Ohio before expanding into amplifier production and relocating its operations to Clinton Township, Michigan in 2016. The brand has developed a following within the metal and heavy rock community, where its hand-built cabinets and amps are valued for their tight low end and aggressive voicing.

The amplifier lineup centers on the Granophyre, a single-channel 100-watt all-tube head designed around simplicity and reliability that covers territory from blues to extreme metal, and the Obsidian, a flagship 2.5-channel 100-watt MIDI-switching head. The company also produces speaker cabinets loaded with its own designs, including the DV-77 Mick Thomson signature speaker developed with the Slipknot guitarist. Digital captures and profiles of Omega amps have been released for platforms like Neural DSP's Quad Cortex, and an official Granophyre Neural DSP plugin extends the brand's tones into the software domain.

Omega Ampworks has 5 products cataloged on Equipboard, including Guitar Amplifier Heads and Guitar Amplifier Cabinets. Their gear is featured by 4 artists, with the strongest followings in Rock and Metal. Notable users include Mick Thomson, Taylor Young, and Bobby Lynge.
