Duck Son & Pinker in Bath was my first thought. Lovely shop - I was wasting my mediocre music talent with guitars back then so I never looked too much at the bass selection but they were always very friendly when I stared wide-eyed at guitars and effects when I only had enough money in my pocket for a couple of plectrums.
also, Stag Music in Trowbridge.
it wasn’t a big shop, dark and dingy. I bought my first ‘proper’ guitar there - a second hand modified Washburn G3V that sits on a wall unplayed for years.
Probably the most significant thing that happened there was a visit by Chad Smith of the Chilli Peppers to do a signing. I’ve never seen the place so busy, and stupidly decided not to bother to queue up to meet him.
