I'm not saying this will never happen, but don't look for it to happen any time soon. Extremely low demand, and - as per usual - adding a TOM is not as simple as it sounds. Programming a TOM bridge would also mean programming a new neck pocket angle. We would need to assemble and test at least one to make sure it's working correctly. Then we would need to photograph and document this new feature, and make the new offering available on the website. Lots of hours invested, plus the "opportunity cost" of all the other work that could have been done with those hours...all to sell maybe one Bass6 with TOM per year.
TOM on the Bass6 is a great idea, but I'm sure you can see why it isn't a high priority from a manufacturer's POV.
