the rbx is about 190 gbp and the thunderbird is 230 gbp. I could get the rbx 5string for about the same price as the thunderbird. Ive heard good things about both of them but im stuck choosing, OR i could save up and get something better. Ive seen people play the thunderbird (shavo) but he had the gibson one i think. ive never seen a band use a rbx374, well not on tv atleast. Im play Rock/metal, maybe a bit of funk and slapping. which bass is better?
