These Scratch Pads work great. I have 2 electric guitars and have one on each guitar. Back in 1980 I bought a very nice guitar that within 3 years of moderate giging I wore through the finish on the back of the guitar, right down to the mahogany and all kinds of worming. The Scratch Pad helps eliminate that damage. I have removed these and put them back on a number of times, it sticks on just as well each time. I also had to trim the last one because it was to big for the guitar. That was easy to do and it works great.Not looking to relic your instrument? Use this for the back and you'll have nothing to worry about.
