The Traynor Custom Special YBA-3 is a 50-watt British-influenced guitar amplifier head produced by Yorkville Sound in Toronto, clearly inspired by the Marshall JTM and Plexi circuit topology of the era. Its two EL34 output tubes delivered classic Class AB power amp character — compressed, harmonically dense breakup at higher volumes — while the two-channel layout offered separate Normal and Bright inputs common to the British amp conventions of the late 1960s. The YBA-3 was the definitive Canadian answer to imported British guitar heads and was used extensively in Canadian rock and blues contexts throughout its production run.
