About Us

Gear Box Pro Ltd. was formed by President and CEO, Mr. John Adams.  With over 30 years of experience in the professional audio industry, his background includes concert production, equipment sales, installation, service, custom manufacturing, and prototype development.  Gear Box Pro is dedicated to producing products that will exceed your expectations. They are physically built like a TANK for that road warrior durability.

In the last number of years, while designing concert touring systems, Adams discovered that interconnection devices that would simplify the assembly actually didn’t exist.  All audio distribution was custom-made, usually in-house, by each touring company.  Often these custom adaptor cables are built out of polarity, causing significant problems with the sound system.  Understanding the significance of correct polarity to ensure proper phasing and the highest quality sound, Adams was motivated to design and produce cable adaptor products that would allow audio technicians to have a polarity correct device available to them as a plug and play solution.

Cable Cube® products were created to make the technician’s job easier.  By utilizing Gear Box products, sound technicians save time on set ups and have expanded their creativity in pre-show designs. Technicians currently using Cable Cube® products confirm that the products save set up time and provide instant solutions as cable routing challenges arise.  The convenience of easily customizing their distribution needs has enhanced how technicians serve their customers. Sound companies no longer custom build speaker level distribution. These off the shelf product solutions guarantee correct polarity at multiple outputs, building confidence in technicians and their projects.

Cable Cube®’s bi-directional connectivity provides endless application possibilities that fit in the palm of your hand. These are the first of many practical product solutions for the audio industry from Gear Box ProTM.

Gear Box products are currently being used by companies that provide production support for Gordon Lightfoot, Blue Rodeo, The Tragically Hip, Canadian Idol (2006) tour, and more. See our growing User List.
