Guitar Center got used Silver Sky SE so I got a 'new' one.... The setup is pretty bad so I'm tweaking but I noticed this..... Now it makes it really easy to adjust the overall height of the strings and is great but I've never seen one not screwed all the way into the body so I'm wondering, is this safe/stable? Is it OK to be adjusting it to adjust string height... I sort of suck at strat setups so it's really helpful to use those screws .
