Hey guys, i recently picked up a new fully loaded JPMM, and it's been treating me great. However, I changed the factory strings that the guitar came with to Blue steel: .46 through .09 and noticed that this guage strings aren't giving me enough tension to keep the bridge "straight" (at same level of the body). I don't want to mess around with the springs or action, so my question is : What guauge strings do the JPMM's come out of the factory with? also .. are they slinky's or what? Thanks in advance duders.
