Well, I hope this counts as helpful. Played a number of 5 string basses (while in the 'early learning' phase ) and landed on an Ibanez BTB575. It stood out because of its solid B string and after getting home, I realised that it was because of its 35" scale. I loved it to bits and found that it differed to a 4 string in a way that I liked. I owned it for quite a while and decided that if I was comfortable with a 5 string, it would be silly not to buy another one to replace my Ibanez, so I bought another one and was still loving it, up to the point where I sold it.
And so now i'm looking for another 5 string to replace it. It sounds strange too, but I didn't get on much with my previous 5 string, whereas my Ibanez made me feel like the B string should be played more often because it sounded to clear and bright.
