Basil Bannayi

"I cannot recommend this business enough. John is the real deal, a man who knows how to transform a tired guitar into a better version of itself."

Steven Cass

"I have had a lot of set ups over the years at different places and String King is by far the best; John listens to everything you say and doesn’t make assumptions about what you want. I can not recommend him enough."


"John literally breathed new life into my 30yr old Fender Stratocaster. The refret was better than the original and with a new nut and set up it now plays better than ever. Fantastic service at a great price."
