Click the play button to start the sound clip. After about 2 seconds in the noise will be heard to drop in volume as I touch the bridge. The sound is still noticeable as the chord is played about 10 seconds in and increases in level as i take my hands off again. This is the classic "hands off" buzz which indicates a lack of screening.
Despite the presence of some fairly heavy duty foil on the scratchplate, screening is ineffective as the circuitry is not fully enclosed by it.
