I saw JD's remark in the For Sale column relating to someone putting threadlock on the threads of these screws. With my Sho-Bud I put small coil springs on the bolt before inserting. Found them in certain makes of cloths pegs. The wife wondered where the cloths pegs were disappearing to.

I can now reach under the guitar and adjust by hand.
Also when adjusting (and I am probably teaching people to suck eggs

} I adjust the thinnest string first as this has the greatest travel, and then the lower strings. Tune the G#, apply the pedal then tune to A with the pedal stop. Now tune the lower G# and tune to A at the changer. That then only leaves small adjustments at the changer.
OK - back to sleep now.
