I went short scale 18 months ago because of neck and arm problems. I have 3 short scale (30") basses, and they have noticeably different playing characteristics. This is mainly because of the position of the neck relative to the body. See Photos. In photo 1, left to right, Lakland hollowbody short scale, Fender MIJ Mustang, Harley Benton Shorty. Notice the different bridge positions relative to the end of the body for each bass. The Lakland's neck projects quite a lot further to my left when I'm playing. It feels much more like a 34" scale bass as a result. The Mustang has a thin, skinny neck which brings my left hand closer in. The HBS brings my left hand even closer in, plus it has a small body, making it feel quite dinky relative to the other two. Howeber, it has the widest neck. See relative nut positions in side-on photos, and see how much "longer" the Lakland neck is.
Kev - don't know where you're based, but you're welcome to pop round anytime to try these basses out for size.
