I think all Schecter basses are thin on ground in UK, not just the Model T. I had to special order my Ultra bass and that took several month to arrive.
I've seen a few posts on the Schecter Facebook page regarding artists using the T, it's well thought of.
...and I just noticed the MA bass has a 38mm neck, that's tempting. Lol.
