The string gauges that Stan specified on his last personal bass with standard tuning were .030 .040 .065 .080
His necks are carved extremely thin, so the strings will pull more forward bow into the neck, but the tradeoff is that a less massive neck will move more. He's got a full time tech, so his basses are always in ready to play condition.
I don't think there is an ongoing debate about shortscale buzz. The fact is that some setups require more maintenance than others, regardless of scale length, so a very slight movement of the neck will be noticed. It's also a fact that many players that seek extremely low action do not have a playing style that acknowledges it. This is just something I've personally witnessed many times in my over 30 years of watching people play Alembic basses.
If we are presented with a bass (or guitar) that is posing a setup problem for customer, we are able to adjust the instrument to play properly. It might require a heat bend. If the instrument is old and well played, it may require a fret mill or refretting. In rare cases, there is a problem with the neck itself, and in those rare instances, we replace the neck. Sometimes, it's just simple adjustments and a lesson to help understand how each adjustment impacts the setup.
