My local shop is PMT in Northampton. They're perfectly good and always friendly. Sadly I rarely use them because I hardly ever buy basses new because of depreciation (and my recent new custom build had to be returned lol so there's another reason I'm likely to stick to 2nd hand in future) and anything that's tech like my helix, wireless stuff, pa gear etc I just buy from whoever gives the best deal online. I know what I'm looking to buy and find this very forum far more reliable when it comes to advice on what to buy than any shop I've ever used (the In Ear Monitors thread is a glowing example of what this forum can give in terms of advice and shared knowledge).
I don't blame PMT for not being my go to shop because, like I said, they're perfectly fine but I just don't really need the advice and of course if you look hard enough you can always find stuff for a better price online.
