On Sunday my lightly built all solid mahogany tenor sat with me through 27% RH and 87% RH. Not locked away like a mummy, but resting against the coffee table where I could pick it up frequently. It travels with me for work and vacations with me in the tropics. I figure if a few years down the road it's bent and unplayable, I'll replace it and still be ahead because there's value in all those accumulated minutes of playing.
