Welcome to the club!
Beautiful Tbird you have there, and she might be a very very rare one indeed!
To the best of my knowledge Gibson only made the exposed pole, coil tapped, Babicz bridge bird for one year. That was 2015. However, Gibson has been known to dabble around with design ideas and prototypes before an official release. If in fact yours was made in 2012 it’s possibly a prototype, I’ve only ever seen one other 2015 prototype (a 2014 model). Or I suppose it’s possible Gibson fabricated the bass in 2012 but didn’t release it until 2015.
A 2015 Tbird will have the words “Made in the USA 2015 Model” stamped into the wood on the back of the headstock below the serial number. Yours should have this, but the serial number is the official build date. Case in point, I have a 2013 Anniversary Tbird but the serial number dates it to 2011 even though the stamp on the back clearly says 2013 model. I can only assume Gibson built the bass in 2011 but completed and released it as a 2013 model.
In any case, welcome to the club and Rock that Bird!
