I dont get the amp opening problems hell i was green and never had any problems with them...Go get yourself a dremel cutting disk or steal one, scratch around the neck 3 times take a pen cap it pops off everytime! Its not rocket science guys....
You really don't have to go all the way around the neck. Just score it w/ a small file. All you need is an etch as little as 1/16". They will pop open w/ hardly any pressure. But as said above, get an amp opener from getpinz.
