If 192P NOS sounds familiar it’s because this is a highly sought-after and increasing becoming rare Capacitor.

It’s widely reported that Slash used the 192P Cap in his Les Paul for the first Guns and Roses album. This cap is well suited for a great fast pick action and great for blues. Great for single coils and humbuckers. It's tonally an incredible Cap

Sprague ® is the Holy Grail of Capacitors for Guitars. Sprague ® created the Bumble Bee, Black Beauty, Vitamin Q and the many variations of the Orange Drop.The 192P is one of my favorites

Crisp sound with clean harmonic content.
