i got some ernie ball power slinkys and i put them on my guitar,tuned them all up and the G string sounds out of tune when played in a power chord that has the D string in but sounds fine when playing the D chord(high E,B) the strings are this gauge>11-14-18p-28-38-48 can play the G string in a power chord if i tune it down a tad tho
You need to set up your intonation for the new strings.
Your intonation's probably just off. Also, if the strings are heavier than what you used before, check the neck bow before adjusting the intonation.
okie dokie thank you!
