my friend had a Ibanez Bass that he smeared with dog crap and then after it dried he shelacked (sp?) over that and he called that his S*&t Bass and he loved the thing (band called Nightstick from Boston)
I knew of another guy here that somehow attached wood to his bass to make it look like a skinny long penis with a penis shaped headstock with two big giant balls down at the body section and he played that live during certain songs and the crowed loved it when he came back carrying it--> like a novelty act but it worked for a decent following at following shows .
I think there is no ugly bass out there,,, its all in the eye of the beholder,,, I had a Pedulla series two that was a yellowish lime green and whn I joined a hardcore band they finally talked me into stripping the finish off and I always wished I didn't becasue I thought it was more funny than anything.
as for sound,,, I'm brought up on the principle that the sound is the head/amp and speaker cabs,,,, any bass can sound awesome just turn around and adjust the setting s OR buy another amp---> there is AMPS that Suk but Basses stand in another category.
