Guitar amp repairs, servicing and bespoke manufacturing


Sutcliffe Amplification are manufacturers of top quality hand made, bespoke equipment for musicians, using some of the best quality British made components. Unlike other manufacturers who claim to be British, we go out of our way to source components from manufacturers who, like us, actually make their products in the UK.

Repairs & servicing

Amp repair and audio equipment servicing based in Waterlooville/Portsmouth, Hampshire. Also convenient for Southampton, Chichester, Sussex, Surrey, Berkshire, Wiltshire, Dorset and surrounding areas. We repair both valve and transistor hifi, guitar, bass amplification as well as effects. We are approved Marshall and Fender repairers and can also repair any kind of electronic equipment, not just restricted to audio.


Amp modifications can be the least expensive way of personalising your favourite bit of kit and we have many ways in which we can help you achieve your perfect tone. Here at Sutcliffe Amplificaiton we have a range of modifications to give you the amp you’ve always wanted at a fraction of the cost. Want more gain, headroom, brightness etc? No problem.

Client testimonials

“Raphael’s knowledge not only saves you money but also brings new life to your cherished sound equipment. We have recently had a number of items mended and refurbished for a fraction of the cost of replacing them and there appears to be no job too difficult for him”

Nick Smith Director of Music, St John’s School Leatherhead

“Raphael offered a quick and professional service, repairing a broken Fender guitar combo and Carlsbro bass head. Not only that but the invoice was far lower than what I might have expected from other similar companies. I’d definitely recommend to my friends, in fact I already have done!”

Gareth Thomas Guitarist for Mayors of Miyazaki

“I’ve collected a number of guitars and amps. It’s been amazing meeting Raphael, who’s been passionate about my gear – his approach to any repair I’ve tasked him with has been great and it’s awesome working with someone you can trust whose quality of work is first-rate.”
