I've been buying basses from Mark and Bass Direct for years. I actually think he owes me shares in the company, now. I have to say that Mark has become a good friend and I enjoy catching up and chatting with him. I have had nothing but amazing, friendly and speedy service. He's always been fair, open and honest. I don't always agree with his opinions but I feel he's just trying to get people to see something that might not have been on their radar when going to buy new gear. I know that if I have an eye on something, I'll get a very honest opinion as to whether it would suit me and the type of music I play because, he knows what I like / dislike. That doesn't mean I'll always listen but, I will take it on board. Anyway, he'll always have my business and I would highly recommend Mark and Bass Direct to anyone. I also agree with a lot of comments here, phone ahead and if you can, deal with Mark specifically plus, take a credit card with a big spend limit
PS I think The Bass Gallery is a wonderful place too. The only reason I don't go there much is simply because of its location and lack of convenient parking. Martin and Alex were always amazing to deal with. We are lucky, as players, to have so many amazing places to indulge in our passion
