I was taught when something goes wrong with your car to fix the least expensive item first; if that doesn't work go to the next thing that costs less, etc., until you finally get the car running. I've a beautiful semi-hollow I purchased from a luthier in Colorado, but I wasn't enamored with the sound; I thought it may be the humbuckers, but like the car I opted to change the strings first. Very glad I did! I've been a D'addario fan for a while now, so I knew I was getting quality, but these inexpensive round wounds brought a depth of sound that was missing. BTW, the courtesy shown me at my local Sam Ash and the effort to help me find the best product is certainly worth a kudo.
