Ok, so you've got a few high-end basses and there's nothing wrong with them. You dig the tone, how they play and they're worth every penny you paid....... Then you've got this lesser, maybe even crappy bass that might be the red-headed stepchild of anyone else's bass collection but you love it. You can't put your finger on exactly why but you can't put it down and it gets a disproportionate amount of play compared to your more expensive instruments. I want to see the basses that hit way over their weight in your collection. The uglier the better. If you understand why the particular bass is so special, please elaborate. I submit my Ibanez TMB310. Definitely on the cheaper end of the scale but that bass has a thump that none of the others have and the neck is super-comfortable. More often than not, I find myself grabbing for that one over the others. So, what's your underdog bass??
