I owned a brand new short scale version of this guitar. It was great, but it is unlike your typical bass guitar and will be quite different from the two you already use. With that being said, it might be cool to have three different types of basses with a variety of tones, feel, weight, etc.
This guitar is great for the cash, and cool looking if you like the style. It is light weight and has a unique tone. The tuning pegs are not heavier/larger ones like on most basses, for some unknown reason. So, that is pretty much the only thing I can complain about.
You can get these new for pretty cheap, and could probably find a used model at a steal.
Plus, the cool thing about Danelectro guitars are they are generally considered "collectible" and hold their value better than a lot of other guitars (that aren't Fenders or Gibsons).
