What I've always heard is that if you're comfortable, the guitar is comfortable. . I live in FL, it gets pretty damp at times, and I've never had a guitar affected, and they all hang on my walls. A decent sized evaporative humidifier should do the trick, they all function the same basic way. I wouldn't obsess over %, unless you live somewhere with central heat and you have acoustics sitting out. Electrics especially are less fragile than most assume.
The truth is that people are most comfortable between 45-55% RH anyway.
That may be true but "people" don't really have any built in set of checks and balances to adjust should something go way cadiwampus. To suggest (and I'm not saying you are) that folks should trust the " if I'm comfortable then to so is my guitar" method is clearly not a great idea.
