It took some work.For context, I installed this on a Sammick strat style guitar.The pickup holes are specifically for round uncovered humbuckers. So, if you are like me and got nice rectangular buckets, you will need a dremel handy.Also, the screws were not in the same place as the old screw holes. In the picture it looked about right, but not. The really annoying part we’re the ones that were close enough the the old holes that the screws went in kind of sideways. Oh wellAlso, the pickup wholes are a little too close to each other. So, by that point I had already modified the pick guard, so I hogged out a little wood on my guitar.Also… this list is getting long… the switch hole was a little too the body, so I had to take another couple centimeters off the body to get a good fit. All in all, it looks good and you can’t really tell once the guard is on, but mindful that you may have to modify either the pick guard or the guitar body itself to use it.
