Came into ownership of a Gibson EB-0 a while back, and learned to my surprise that the bass that had been on my want list for a while was actually the same scale as your average guitar. Other than the issue of getting accustomed to the smaller frets, are there any special concerns to be aware of (gauge, string tension, intonation, etc.)?
It's true that EB-0 has a short scale length, but not as short as an "average guitar". For example, a Les Paul typically has 24.75"; or 25.5" for a Telecaster. EB-0 has a scale length of 30.5", while shorter than most basses (which are around 35"), is still much longer than most guitars.
With the same tuning and string gauges, shorter scale length means looser strings, which is easier to fret, brings warmer sound, but also more prone to fret buzz. To my personal experience, it also takes more effort to get shorter-scale guitar/basses in tune, but that won't be a great issue for well-made instruments.
Finally, you can always increase your effective scale length by using a set of thicker strings. After all, it's all about tension.
