Hello all,

I've got an Epiphone LP with P90s.

I just raised my action (slightly) to get rid of some unwanted fret buzz. Does this mean that I should raise my bridge pickup (or neck)?

No, its should be fine, as the strings will only have moved a millimetre or less MAX, providing you were happy with the previous tone.

yeah the tone before I made the adjustment was fine. I just wasn't sure whether raising the action would dampen the sound or anything.

Thanks MCK
You can raise and lower the pickups very easily, so if you feel they need adjustment, give it a go, you can always put it back in less than a minute
