recently i replaced the strings on my mtd beast, wow what a difference. i got some ghs Boomers, loved the sounds, that fresh brightness, and they still sound good, nice and even throughout, and the highs aren't harsh like they used to be. however i can already hear the strings mellowing more than i want to, they are ok now, but what can i do to keep myself from buying a new set of strings every month or what not?? i know elixers last a LONG time, but i also heard they are definately mellower. any ideas on a long lasting string that stays pretty bright??
