McAvoy first began his musical career in the Belfast band Deep Joy. During his tenure with Deep Joy he first played with drummer Brendan O'Neill, who was later to tour with Rory Gallagher and appear on Gallagher's last three albums Jinx, Defender and Fresh Evidence.
McAvoy began listening to blues records at an early age. As well as rock and roll, his main influences include Muddy Waters, Paul McCartney and Jet Harris. In his autobiography he cites his brother-in-law (of the same name) as an influence on much of his musical taste. He mostly plays Fender bass guitars, particularly Precisions, owning a 1955 butterscotch blonde Precision and a 1975 cream Precision. However his main stage bass guitar is the black Music Man StingRay. He also owns a black Silvertone bass. For amplification, he uses a Trace Elliot V6 amplifier and a 4 X 10 speaker cabinet, a Peavey T1-15 and a Marshall bass 30W.
