Peter Traynor began working at a Toronto area music store as their electronics repairman. As a musician himself, Pete not only had an exceptional understanding of the electronics he was routinely working on, but he had an inherent and unique understanding of the limitations and the frustration players were having with the product available to them at the time.

Seeing an opportunity, Peter developed a bass guitar amplifier dubbed the "Traynor Dyna-Bass" as a rugged and reliable alternative to amps currently available at the time. The Dyna-Bass amp was specifically designed and built to withstand the rigors of rentals and the road and became an instant hit with musicians in the Toronto area.

Yorkville Sound Limited (Traynor's parent company) was formed with storeowner Jack Long as president and Peter Traynor as vice-president. By the mid-60s, Traynor products began appearing in more and more independent music stores across Canada with artists like Chuck Berry, John Lennon, Eric Clapton, Jeff (Skunk) Baxter and Steve Miller finding themselves playing through Traynor stacks.

Traynor Amplifiers are still manufactured by Yorkville Sound, a privately owned, wholly Canadian Company manufacturing a full line of professional PA products including mixers, amplifiers, active and passive loudspeaker cabinets and lighting - employing over 250 people at the 225,000 square foot Pickering Ontario manufacturing facility.
