Quick Question: I currently play a pair of Gamma Ipex 7.0 MP's that were strung with TNT Fatcore 16 at 62lbs (on a dropweight). I finally broke both strings tonight, so it's time to get a restringing. Thing is, I thought the stringbed was too tight, and I plan to drop tension a bit. How much tension should I drop at a time? 3 lbs? 5 lbs?
