Epsom used to be my local store. When I was buying my 4003s, the truss rods needed adjusting and the tech did it with speed, ease and accuracy so I could have a better demo experience. This turns out to have been no mean feat, I tried adjusting the neck some months later, having bought it and made an initial pig’s ear of it. I also had an Epiphone Casino, with Bigsby, totally set up, including fret levelling, by Epsom. When I picked it up it was a different playing guitar, real quality. I can only hope that my new ‘locals’ are as good (I can’t think why they wouldn’t be).
