This King Silversonic is exceptionally well preserved, it has been played very little.  The pads are original along with everything else including the original packing label, factory inspection tag and King Instruments catalog 1970 with a price of $835.00!  It currently plays, fairly well but being original pads it will need an overhaul for sure.  It’s in very nice condition and plays with a rather huge muscular and flexible tone. Many people would say that this mid 400-serial is the best period for King Silversonic.
