As a young man, Traynor played guitar in three bands with Robbie Robertson: Robbie and the Robots,[2] Thumper and the Trambones, and The Suedes.
[1] Traynor worked as a repair technician at Long & McQuade's first store in Toronto.
In the 1960s he began designing specialized sound amplifiers and other related equipment for the store's customers.
[5] His hand-wired bass amplifier, which he called the DynaBass, was in demand, so Traynor teamed with his employer Jack Long to create a company, Yorkville Sound, to manufacture and market the products he designed under the Traynor brand.
[7] The Traynor line of equipment has been sold worldwide and is manufactured in Pickering, Ontario.
