I prefer Stands but I think wall mounts have no negative effect on the guitar unless it's not in the wall properly and the guitar falls down
I leik music
I prefer stands too, but I'm moving into a smaller room and I won't have the room for them on the floor I don't think, so I'd like to mount them, but I won't if it does bad things to the guitar.
I've had 3 of my guitars on wall hangers for the past 4 years. No problems.

Why, yes, I am a lawyer- thanks for asking!

Log off and play yer guitar!

Strap on, tune up, rock out!
I have 3 guitars, JEM 555, Yamaha RGX420 DZ, and an Encore Strat.

I use both but not the Encore regularly.

And okay, cool
Why not get one of those 3 way guitar stands? Im sure it wont take up too much room

I have 2 guitars and use wall mounts for both (fretrests specifically), they work fine.

Well... There are guitars at Guitar Center than spend years (I'm serious, this one fernandes was there from my first visit 4 years ago to now) on a wall hanger and they seem fine.
