my foray into the Short scale world was pretty interesting. I tried quite a few basses but settled on the Ibanez TMB30 and the Squier CV Mustang as well, they were inexpensive and well...in stock at the time I bought them. There were more I wanted to get my hands on and/or consider buying but they simply weren't available.
Between the two, I thought the Squier CV Mustang was the better choice for me, but I still ended up selling it. Why, because I wasn't particularly fond of the finish of the one I bought used, and stores were out of stock with the surf green option, also I wanted to try a Fender PJ Mustang but couldn't get my hands on one.
That being said, I do have a Mid-scale bass, a MIM Fender Urge modified with EMG pickups that seems to work very well for me. It's 32" scale but about the size of a short-scale due to the small body of the bass, in terms of playability, it's closer in feel and sound to a regular scale bass. Still, a true short scale would be nice to add to the collection as they have a unique quality all their own so the search still continues.
