Nuñez Amplification is a boutique builder of handmade tube amplifiers, speaker cabinets, and effect pedals. The company was founded by Jonathan Nuñez — bassist and producer for the Miami sludge/heavy rock band Torche — in collaboration with Gary Phillips of OvertoneWorks, with a focus on gear designed for extended-range and low-tuned playing.

The lineup centers on the Annex MKII, a high-powered guitar head, paired with 2x12VL and 4x12VL speaker cabinets. On the pedal side, the brand is best known for the Tetra-Fet Drive, a discrete Class-A overdrive with a three-band EQ aimed at delivering tube-amp dynamics in a stompbox, alongside the Annex Bass Channel preamp/overdrive and the Dual Range Boost.

Products are built in the United States using parts sourced from Switzerland, France, Germany, Japan, the UK, and the US. The brand has developed a niche following among heavy guitar and bass players, and has been covered by outlets including Premier Guitar and Guitar World.

Nuñez Amplification has 3 products cataloged on Equipboard, including Overdrive Effects Pedals and Boost Effects Pedals. Their gear is featured by 6 artists, with the strongest followings in Rock and Metal. Notable users include Tom Polzine, Jonathan Nuñez, and Tim Lash.
