I got a short scale Gretsch Junior Jet 2 (4 string) a couple of years ago.
For the money, it's a lovely instrument & very easy to play, with LOUD output from the mini humbucker pickups.
Others on here have used flatwound strings on short scale basses, I left mine stock (roundwound). I find the 'bendiness' of the strings on mine a bit disconcerting, but thats in comparison with a full-scale bass.
I'd recommend trying one (or any short scale bass) before you buy - it may be the 'one' for you, or not.
@Skinnyman bought the same bass recently, he might be able to add his thoughts.
