I just buyed a new guitar for 2000$ and I want it to stay perfect for a long time so I would like to know in what kind of conditions I should keep it. I have an hard case if that help... Should I buy a humidifier? What is the perfect humidity, temperature etc...

TY!

Tsss, it's a Jackson Sl1 for people who want to know!

Simply put: if it's an electric guitar....don't worry.

They need very little attention - as long as you don't hang one directly above a radiator or whatever you'll be fine. Guitars which are nitro-finished can be damaged by sudden changes in temeperature (eg. getting to a very warm gig after walking in the snow), but most Jacksons have modern polyurethene finishes so there's really no cause for concern.
Take care of that axe!
