Lately I've started going up string gauges due to a guitar which lacks good tone and for finger strength which mine is too bad I guess. (F#*king Ltds :( ) Well today I put on some 12-54's but I read on some stuff from the forums on Ultimate Guitar and i feel the advice on that site is rather stupid and sounds like people who have just started guitar giving advice so I thought Id come here for it
The questions are
What effects will having a heavy gauge do to my guitar?

I've set the intonation and now play in E Flat
Is there anything else I need to do and should I tune even lower?

Thank you (Dam Ultimate guitar :mad: )
