I know that LOTS of people love their Warwick Thumbs so I had to try one... Brought my kid with me and we tried out several basses (all 5 string)... here's what we found: Warwick Thumb (bolt)... VERY heavy, VERY VERY neck heavy, plain looking wood, OK playability... not very fast, good sound. Pedulla... nice looking, nice sounding, but had a strange neck profile (thin and wide) that kept me from falling in love. Music Man... butt ugly (kind of a solid paint pearl pink/purple), sounded great and played great. Zon... absolutely beautiful wood, great tone, light weight and balanced, played the best of them all. OK... you can all trash me in a minute... these are all just MY (and my sons) opinions... but my Carvin sounds and looks better than all of them except for the Zon! I would also have to say that the Music Man had a certain punch that I can't get out of my Carvin. So why do soooo many players use Warwick... I just couldn't find the magic!
