I no longer own a T-40, but I just remembered an oddity regarding my third and last one. The neck pocket seemed to be off-centre (towards the treble) so the edge of the neck hung off the body slightly. This in no way affected the playability of the instrument, but I'm surprised that this instrument should have differed from the previous two. Was this a deliberate change in design or could the computer-controlled woodworking machines have actually got it wrong? Just interested...
