Just my opinion -- worth the price you paid: For an older well-seasoned guitar, 35% is on the edge but not immediately deadly. My house drifts down there from time to time, then I start humidifying them in their cases. I would not let a newer guitar go below 40% for very long -- more than a day. Felix, the glass-doored case with dampened sponges inside is a good idea, just an extension of a humidified case.
