As the title says
Probably your local guitar shop. Wrong forum, also.
I think RnB Music in Crewe does it?
RnB Music in Crewe is shit. Only things that shop is good for is strings and plectrums. Possibly Guitar Amplification or whatever it's called in Crewe too. It's down Edleston Road, near RnB. If not, I'm not really sure. I'm trying to find a shop near Stoke-On-Trent, or even Cheshire to get my guitar set up.
