I bought this Warwick bag, marketed as a DJ bag to carry 50 vinyl records, as an all in one gig bag to carry two micro bass amp heads, several leads, pedals and anything else I need on an average night of gigging.
The size is perfect. It easily takes two Markbass size heads, three instrument cables, plug board, four pedals, power supply and patch leads with space for a few more things if needed.
I bought it thinking that if it's designed to carry 50 vinly lp's, a considerable weight, then it should handle all I needed it to. It does and it doesn't. The actual bag part and straps are doing a great job, but some of the stitching on the top of the case (which is just used for opening and closing, and on the padded handle, has already started to come apart after only a few months use. So I expect to do some repairs soon but for the most part this is a good product for the price.
