Ex-pro is a Japanese audio gear manufacturer founded in 1986 and based in Fujisawa, Kanagawa Prefecture. The company built its reputation on instrument cables, wireless systems, and signal-chain accessories aimed at electric guitar and bass players. Its FL Series shielded cables are the brand's flagship product, built around a proprietary HIIIX dielectric material that the company markets as achieving roughly 50 pF/m of capacitance — among the lowest figures available for instrument cables — paired with custom-machined brass plug housings. Other cable lines include the FA, OP, AC, and DC series, each tuned for different tonal characteristics.

Beyond cables, Ex-pro produces wireless systems for live use, including the rack-mounted 10Z Series, the PW Series pedal-format wireless receiver, and the T-100/R-100 in-ear monitor system. The product catalog also extends to power supplies, attenuators, and small utility pedals. Ex-pro gear is sold primarily through Japanese retailers such as Sound House, Rakuten, and Amazon Japan, with limited international distribution mostly via Reverb and eBay.

Ex Pro has 5 products cataloged on Equipboard, including Instrument Cables, Effects Pedal Accessories, and Overdrive Effects Pedals. Their gear is featured by 12 artists, with the strongest followings in Rock, Metal, and Electronic. Notable users include Pata, Yusuke (Lynch), and Toru Kitajima.
