I've had SX "J" and "P" shorties, an MIJ Fender Mustang RI and a Reverend Dub King. But my hands-down favorite shorty is the Guild Newark Street Starfire re-issue (available in either one [SF-I] or two-pickup [SF-II] versions). In addition to having a short scale length, Guild SFs and Mustangs have narrower nut (1.5") and string spacing than many and I find that makes them very comfortable to play (opinions may differ on that). With some diligent hunting, Guild SFs can be had with HSC for under $1K new and for $600-$800 in excellent used condition. A couple of random but useful things to know: •Mustangs have only 19 frets (if that makes any difference to you). Some vintage Mustang bodies have a factory, belly-relief cut but most Mustangs do not. Some have a 7-1/4" fretboard radius and vintage frets and others a 9-1/2" radius and medium-jumbo frets (depending on model). Most have a string-through type bridge which may require the use of a medium-scale string set (depending on string brand). The relatively-new Fender Mustang "PJ" is the exception and does not have a string-through bridge. Guild Starfires are another shorty that will likely need medium-scale strings, due to their unusual bridge design. The Reverend Dub King bridge allows either top-loading or string-through stringing, which broadens your choice of strings. •Shorty strings may feel "looser" or "more rubbery" if you are used to playing a 34" scale length (lower string tension being a function of the shorter scale length). In general, many tend to suffer from some lack of definition on the first few frets of the E string (relative to a longer-scale bass). In my experience, this can be mitigated by using higher-tension, flat-wound strings (e.g.: D'Adarrio Chromes). •Pay attention to short-scale bridge placement. Some of them (e.g.: the Dub King, Guild SF) have the bridge placed further away from the edge of the lower bout (where the string button is) than others (e.g.: SX, Mustang). This will mean that the nut is a bit further away from your body when you are playing, which makes the bass feel a little bit more like a 32" or 34" scale bass ergonomically. When people complain that shorties "feel like toys", they are likely referring to shorties like the SX or Mustang which have the bridge placed closer to the lower string button (in addition to having physically small/narrow bodies). •SX basses are a decent value for the price, but pups/electronics are definitely their primary weakness. Probably would be wise to factor the price of replacement pots and pups into your budget calculus if SX becomes a serious option for you. That said, the basic platform is good enough to be worthy of an upgrade. I put DiMarzios (DP-123s & DP-127s) in mine. Hope something in all that helps. Good luck with your quest!
