Thanks for that insight,
Bryan. Yikes. Better to split the Bridge Doctor than some aspect of your guitar. I have no experience in the matter, but
apparently tightening the JLD device very gradually (spanning multiple days) while actively humidifying
might enable more movement of the device's rod and the guitar's top, while lessening the likelihood of damage.
But having read
JonWint's comments I see that the most important factor is whether or not the bridge has tipped downward toward the sound hole. I have to find a straightedge to place upon the spruce top that will fit between the bridge and just shy of the top edge of the soundhole. If it dips into the hole any noticeable amount, the JLD might help.
At this point, the spruce top looks to be
flat from bridge to fretboard, so the JLD Bridge Doctor may be irrelevant.
