2006 Warwick Dirty Blonde 4-string (pic heavy) FS: Warwick Dirty Blonde 4, Jaco Fretless, Gibson LC-1 Warwick Thumb 2006 LTD Dirty Blonde FS Warwick Thumb BO LTD 2006
There are four Dirty Blonde sale threads from TB Classifies, with the price ranging from $1100-1400. Warwick's cost a lot new, but don't have much for resale value unfortunately. However, once you grab them used, they tend to hold their value pretty well it seems. That being said, lsu921 was about spot on with his estimate.
A NT Thumb will go for more (typically $1800-2000 average from what I've seen), but Bolt On Thumbs (even limited editions) don't go for as much. A standard Thumb BO will range from $800-1300 depending on year and condition. As for streamers, it all depends on the model. A Streamer LX, $$, or Pro M typically ranges from $800-1200, a Jazzman around $1300-1500, a Stage I around $1500-1800, and a Stage II from $1600-2000. Sometimes you'll find stuff for less than the normal range, sometimes more.
