What I do

Guitar Aid London - guitar setup amp repair modding workshop and services Are you looking for a specialist to repair and modify your gear (amplifiers, pedals, etc.)? Are the pots in your amp scratchy? Does your amplifier need a new set of valves? Is a switch in your favourite stomp box not working?
Have you changed strings recently? Is your guitar out of tune - need an intonation set up? I can help you.

I also do modifications (extra FX loops, changing FX loops from parallel to serial, tone controls, extra switches, pedals, etc.). I am very experienced in guitar amplifiers repair, design and customisation and I am fully qualified with a BSc in Electronics.

I am passionate about gear and will always offer you whatever solution I think is best for your needs, regardless of whether or not it brings me work!

I offer expertise, excellent service, quick turn-around, and all at reasonable prices.

I stock spares for all popular makes of guitar equipment. I am an agent for WD Music and AllParts UK. I also fit original Marshall, Mesa, Line6, Hughes & Kettner, Ashdown and Peavey parts.
