Napper has always been very helpful when I've dealt with the Bass Centre. I obtained my whole rig from there, and although they had supply problems with the last cab I bought I emailed Napper and he responded quickly with an accurate estimate of when I would get my cabs.
Its concerning that other people have had cards cloned after shopping there however - the first time I shopped there I had £500 rinsed off my card by cloning and had to have it cancelled and refunded by the fraud department of my bank. Coincidence?
