Hi guys,
I got las week my first PRS, an SE C24 35th Anniversary.
Overall, I am very happy with the guitar: good finishes, beautiful top, good mechanics and a sound with tons of personality. I love it.
I am only concerned by one topic: noise.
As I said this is my first PRS, I come from an SSS Stratocaster and I expected to have less noise on a HH guitar. Unfortunately it is not the case.
In summary: when I plug the guitar in and use high gain I notice a strong hum that diminishes when I touch any metal part with my hands. When touching any metallic parts the noise is acceptable and lower than a single coil.
This made me first doubt about circuitry: grounding issues or cold solding so I opened up the back covers and checked (I am electrical engineer so I have a decent experience doing so) with a multimeter (diode tester) and found that all metallic parts (bridge, pots back covers, all ground solding, jack ground plate, blade switch) are well connected between them, no weird impedance, just full conductivity.
I also noticed that while the back, detachable covers are conductive, the inside wood cavity is not. just painted in black (which by the way is very well done) but no conductivity at all. This makes me think there is no Faraday shielding.
I just want to make sure that such configuration (no shielding) is standard and having such noise is a common behaviour.
Also, has anyone tried to shield pick ups and cavities with copper tape? does it reduce noise?
I was about to send the guitar back to the shop for replacement, yet I doubt it is something that happens on all PRS SE.
Can you help with some advise?
