I've had my Modulus Quantum 5 for about 3 months now. I have yet to touch a thing on it, besides changing my strings. On my E and A string, whenever I hold down fret 3 (up to 6), it rattles against the closest fret producing a buzz. Should I raise my action to stop this? If so, do I raise the action of all the strings? Tips for doing this or any no-no's? Thanks in advance.
