When not being played, my basses and guitars go back in their case. I used to think it helped keep the neck straight -- not only as a physical 'cast,' but also keeping the instrument away from any fluctuating humidity in the air. I also like the fact that my instruments stay dust free when in a case. But, I pick up my instrument more when its on a stand, staring back at me constantly. I practice more... I write more when its on a stand. So, does it keep the neck more straight? Does humidity affect it less when in the case? What do you guys think? Where do you keep your instrument when its not being used and why?
