Rooted in Pub Rock Royalty: The Birth of Cornell Amps
Growing up on Canvey Island alongside Wilko Johnson and members of Dr Feelgood, Denis Cornell shared a close bond with the band as both a friend and fellow musician—frequently sharing stages and performing alongside Steve Hooker.
In 1991, as Dr Feelgood’s success continued, frontman Lee Brilleaux asked Denis to engineer a custom amplifier tailored specifically for his high-output Shure Bullet harmonica microphone. That historic build marked the very first amplifier to bear the Cornell name.
Later in the 1990s, legendary guitarist Wilko Johnson sought out the Cornell Custom 40, meeting Denis at the iconic Club Riga venue in Southend-on-Sea. Captivated by the amp's dynamic response, Wilko requested a precise modification to the treble circuit to perfectly complement his famous red-and-black Fender Telecaster. Denis custom-tuned the circuit and went on to build a bespoke amplifier wrapped in matching custom cosmetics—a testament to two Canvey Island originals shaping British tone together.
