Anyone have a Yamaha TRB411, or a Peavey Cirrus 4 Bolt-On Mahogany?

I'm currious about these two basses. I own them. I'm not a bass player per say. I'm a guitar player. I'm learning the bass. Which is a totally different ball game as anyone who's tried to play bass can tell you. It makes you have alot of respect for the good bass players you here.

The reason I'm asking the question about the above basses is i'm thinking of getting rid of them and getting one real good bass. I know this will not correct my problem of not being a bass player, only practice will do that. But I'd like some advice from real bass players.

Thanks
