You know that bit in the first Harry Potter film where he goes into the wand shop? That's Mark at Bass Direct...
Seriously, I found on my first visit that I asked to try what I was initially interested in, he set me up and went into the office to answer the phone and do some clerical stuff, then came out a couple of times to suggest other basses/amps I might like, based on what he'd heard. It was a bit of a shock at first, and I could easily have taken offence at his bluntness, but after I'd gone with the flow, I found he was bang on the money. He's a real enthusiast, but to get the best out of the experience, you need to leave your ego in the car...
