Hi everyone, I have just bought a new PRS SE Custom 24 and I'm delighted with the sound, feeling, action and look of my guitar. However I feel the tone pull push knob much more easier to turn than the volume one. Is it normal or is this a sympton of future problems? If it is not normal, can I tighten the knob by myself or I have to claim to the guitar shop? Thank you very much and regards.
