Hi, gang. I seek counsel of the experts. I'm dropping this in the Amps forum, because amps & electronics are my main concern with this, but I'm hoping the mods will allow the question & answers to go a little bit beyond just amps. I have a ~600 sq. ft. poolhouse behind my house. It's a separate structure, well insulated, and it has an AC/heat unit similar to what you'd see in a hotel room or a school classroom. For the foreseeable future, the band and I are using it as a rehearsal space, and much of the gear is parked in a large closet. Trouble is, when life gets hectic, we may go a few days at a time without getting out there. Presently I have a tube head, bass cab, PA powered mixer and speakers, a couple of mics, and the drummer's drum kit in the closet out there (I'm not leaving basses or guitars for humidity reasons). If the temp. gets cold outside, it can get down in the vicinity of 50 deg. F inside the poolhouse, and if the temp. gets hot, maybe in the neighborhood of 85 deg. F. On the days we practice, I do make sure to get the temp. up to normal at least a few hours before - but I'm not sure that's enough. So the question - any concerns you guys know of / issues you have had with storing gear at these temps? Amp heads and cabs, of course, but also drums, mics, etc?
