I apologize if this is a repeat question(s), but I'm relatively knew to the forum. I recently bought a new Squier Classic Vibe 50's Precision. I am considering replacing the stock pickup with a Bassline SCPB-3. My question is when the new pickup is installed (I would use a professional who presumably knows what he is doing), does he need to remove the pickguard, volume/tone pots and scratch plate and anything else while he's at it? I had a bad experience in the past with an MIM Precision that I upgraded, and it was never the same, always humming when I took my hands off the strings, no sustain, and a few other problems I won't bore the Forum with more than I already have. Thanks in advance for the advice.
