“I had Ilitch Chiliachki (inventor of the Suhr Backplate system) “silence” my ’56 Gibson Historic LP w/ P90s…absolutely amazing how quiet it is without messing with my tone at all.
Made it possible for me to crank my Paul through my Naylor amp loud as balls without the crazy noise & hum that was there before…”
