Opening a guitar shop is quite a commitment in this day and age for various reasons (rent and other bills, price competition, stock levels etc) but he must have done his homework so the best of luck to him. I guess there is quite a bit of footfall around that area so hopefully he'll be busy, possibly more with repairs, setups etc, as they are something that many people are happy to pay to be done and they can't just buy online. Speaking of the latter, hopefully not too many trying out instruments in the shop then buying elsewhere online cos it's £1 cheaper.
Good to hear of a new shop though.
