The inside of this guitar has now had two coats of graphite impregnated lacquer. Brush coating is a rather more efficient way of applying it than spraying it and produces a heavy durable coating. Once dry the surface can be burnished with dry graphite powder to further improve conductivity.
At the start of the sound clip the only sound audible is a very slight 50hz hum, the normal ambient hum experienced with cheaper leads and basic practice amps.
