another +1000 for the guitar store in Soton, i contacted Wes a couple of days before i had to go and lay down some leads for a mates CD, but wanted to test out some boutique OD's, he said he'd dig out as many as he could find in the store and idrove down from salisbury to test them out at full roar at 10am, played for 45mins with no sales pitches and left with an MI Audio Tube Zone
I'll give them another +1000, Wes is top notch and the other guy I spoke to was sound as well, not pushy at all. Both were happy to get down the guitars for us to play with, even when we were A / B'ing guitars to see which was best. They got our business too. (NGD post coming soon). The only thing they insist on is that they take the guitars off the wall for you to play, as Wes said "I'd much rather I ding this than you", which is fair comment on £1800 Les Paul's.
Edit: Oh and to take Johnathan's point, The Guitar Store actually sent out one of the guys to buy us coffee's while we played. That's the kind of service that gets my money even if I can find it cheaper on eBay.
Another Edit: Wes also delivered a guitar we bought previuosly from them. We'd tried it at the weekend, decided to buy it when we got home, I called up on Monday, paid over the phone, and he delivered it that evening.
