Best-Tronics Mfg., Inc. is a family-owned contract cable manufacturer headquartered in Tinley Park, Illinois. Founded in 1973, the company produces custom cable assemblies, wire leads, and harnesses for the military, telecommunications, medical, broadcast, and professional audio industries from a 60,000 square foot facility. Its professional audio line, Best-Tronics Pro Audio (often shortened to BTPA), serves musicians directly with built-to-order cabling and pedalboard integration services.

The BTPA catalog centers on pedalboard patch cables, guitar and instrument cables, MIDI cables (including 5-pin, 7-pin, 13-pin, and TRS variants), speaker cables, XLR and microphone assemblies, and custom snakes and looms such as the Composite Cable for pedalboard rigs. BTPA also produces specialty footswitch cables for a wide range of amplifier brands and dedicated cable sets compatible with modelers like Fractal Audio and Kemper units. All assemblies are hand-built to order in the U.S., tested for continuity and isolation, and assembled with WBT silver solder by operators trained to IPC/WHMA-A-620 standards.

The operation is run under a "Made for Players by Players" philosophy, with an owner who is a working musician. BTPA is commonly associated with rig-building and pedalboard wiring for touring professionals, and its products are stocked by specialty pedalboard retailers such as Vision Guitar and Custom Boards.
