Well known for powering the backlines of guitar gods such as Guthrie Govan, Richie Kotzen and Rabea Massaad, Victory has also had considerable success in the pedalboard-sized preamp and amp niche with its award-winning V4 series. 

The V4 guitar amps are intended to reproduce the tones of Victory’s full-sized heads but in more portable packages, and feature a clever valve preamp section hooked up to an ultra-compact 180-watt Class D power section, with a smooth digital reverb.

He built his first valve amplifier at the age of 12 and has since bought, sold and restored many more, with a particular interest in Vox, Selmer, Orange and tweed-era Fenders, alongside Riveras and Mark Series Boogies. When wielding a guitar instead of soldering iron, he’s enjoyed a diverse musical career playing all over the UK, including occasional stints with theatre groups, orchestras and big bands as well as power trios and tributes. His favourite musical genres are ‘anything that’s good’.
