*27 years ago* I started using GHS Super Steels, but they became harder to find as the years went on. So I switched over to GHS Boomers and haven't looked back. I use .010 - .046 gauged sets on my Fender Telecaster and Gibson SG. I use .011 -.049 gauge on my Gretsch G5120. They produce a great tone and good sustain. A brand new set settles in quickly without a whole lot of stretch and re-tuning. I tend to manually force stretch a new set of strings anyway. They maintain their brightness for a long time before starting to sound dull just before a string change. I do change strings often (as often as every week) depending on how much I play. I recently bought a 5 pack of D'Addario EXL110 on sale, but I'm not happy with them. I'm way too used to the GHS Boomers - to me, putting on a new set of Boomers is like putting on an old pair of just washed blue jeans that are fresh out of the dryer.
