Being a pro/semi pro guitarist for the best part of my adult life, and doing a lot of recording and live sessions, lately felt the need to change my strings on my Acoustasonic Tele's more frequent to keep the "fresh" guitar string feel longer...but with the standard bridgepins it is always a hassle to change strings...but with the Power Pins installed I can change my strings fast and without problems. A major upgrade for these guitars, the Power Pins also provide a bit more sustain to the instrument. If you're looking to upgrade to these pins, do it yourself, I installed them myself in about 15 to 20 minutes, never going back to standard bridgepins...
