Inverted Cross Audio is a boutique builder of handcrafted guitar amplifiers and effects pedals based in Barcelona, Spain. The company was founded in 2016 by Ben, an electronic engineer who studied audio electronics at Valencia polytechnic and began his journey building amplifier clones of circuits like the Soldano SLO-100 and Mesa/Boogie Dual Rectifier before moving into pedal design. The operation is run hands-on, with circuit design, PCB fabrication, enclosure etching and drilling, and component soldering all done in-house.

The product lineup leans toward high-gain and experimental tones, with pedals such as the Hemlock, Hammer, Octane, Bitzilla, and Omega preamp, along with an HM-2-style clone and Sunn Beta Lead-inspired B3T4 preamp that reflect the builder's roots in metal guitar. Pedals are typically offered in multiple enclosure formats — a standard side-jack version, a top-jack clickless variant, and a compact micro version — and many units ship with custom acid-etched artwork. Alongside finished products, the brand sells DIY kits and PCBs for builders.

Inverted Cross Audio has 1 product cataloged on Equipboard, including Distortion Effects Pedals.
