I have a 2006 Warwick Thumb 5 Bolt-on for sale. I looked up the serial number on Warwick's website and it states that the bass was made Feb. of 2006. The bass is in good condition. It comes with a heavy padded Warwick gig bag as well as the manual and adjusting tools. I'm considering the following trades: Sadowsky UV70 Sadowsky MV4 or MV5 Vintage RI MIA Fender Jazzes Vintage RI MIA Fender P's (like MrDak's) Lakland USA JO Warwick Streamer Stage II I'll add cash where necessary. Thanks for looking! Beautiful arched back makes it very comfortable to play.
