I only ever set foot into Aroundabout Sound in cheltenham, as it is run by two of the nicest people ever. They let me play for hours and i buy a pick, strings, leads, etc. Top people, good range of basses. Talk for hours with the male owner, plays either a Goodfellow or a Jazz from the first month of production (the most mojo'd bass i have laid my eyes on) into an EBS stack.
He knows what he's talking about, and just gives plain honest advice to you about every single bass. Even gives you some tips as your playing!
