I never went to the Wapping shop, but the first few times I went to the Bass Centre on Brune St I was served by a Guy called James (I think) and he was a legend. That might have been 'cos I was keen on buying a Thumb bass and he was selling one himself through the shop, but because he was a nice guy and a good salesman I went £400 over buget and got the bass I wanted instead of settling for something I could afford. I bought a little Hartke practice amp from him too after that, but unfortunately he left the shop.
After that I found out a guy who used to work in my local Academy Of Sound had got the job of manager at the Bass Centre, I guy called Deano. I went in and saw him a couple of times but he was mostly upstairs with the skinny stringers. The service and just plain friendliness of the staff in general seemed to have dropped. I tried out a few pretty pricey basses one day and the guy downstairs just didn't seem to be taking me seriously if he was taking an interest at all. I do tend to try out basses that my skill level doesn't warrant, but they shouldn't assume that I wouldn't buy them all the same. Shame, but like others have already said, the variety of stock they were carrying seemed to be diminishing as well as the service.
The Bass Gallery has always had amazing stock, but I've never quite felt comfortable in there. That's not to say that I've been made to feel UN-comfortable by any means though, maybe it's that thing I mentioned before about my playing not being "all that" just lurking at the back of my mind and feeling slightly out of my depth in there. The fact that it's TINY in there makes me feel a bit on display whenever I've tried stuff out too, but I think that's probably in my head. I just get a bit self concious when I know I'm around other bass players I guess!
What about the shop half way down Denmark St? The one next door to a guitar shop that's fronted with the same colours. They've always seemed alright in there to me, anyone else got any experience with them? Is that place even still there?
A friend of mine has recently moved back to Essex so I'm hoping to make a trip to see him and visit the Bass Merchants too, I don't really have anything in mind that I want, but I do enjoy a good days bass shopping! Can't get that online, which I think has been most people's point on this thread so far. I'll stop rambling now.
Cheers!
