Cool idea, I'd also be interested in knowing when they moved to the spokewheel truss rod adjuster.
That is the greatest Sadowsky 'perk' ever. I love it; it makes my life so much easier when I change strings or when the seaons changes. I keep my guitars and basses in a room with radiant heat, humidifer, and central AC. But still, every so often I need to make a slight tweak to the truss rod.
TOTALLY ! With the constant humidity fluctuation that my city goes through - tweaks are part of life. I'm looking forward to this one !
