How can I mount stuff to the walls without wallmounts?

<!-- SC_OFF --><div class="md"><p>So I have a couple things I want to mount to the wall</p> <p>1) my guitar&#39;s for decoration </p> <p>2) my PS4 console for cable management.</p> <p>How ever, due to my lease I&#39;m not allowed to put nails in the wall. I was considering on doing it and then repairing it with drywall fix. But I just want to know something I could use that could mount it without damaging the wall.</p> <p>Something like gorilla glue or something? What could work? </p> <p>edit : would gorilla tape work? <a href="http://www.gorillatough.com/gorilla-mounting-tape">ps4 is only 5-6 pounds</a> and a guitar is about 8 pounds. </p> </div><!-- SC_ON --> submitted by
