VIP 550k LONG Shaft Audio Pots Centralab Specs (The Holy Grail of Guitar Potentiometers)

Yellow Varnish Spaghetti Tubing


VIP Potentiometers


"In the late 50s, Gibson (and others) preferably used potentiometer by US maker Centralab. The audio taper of these vintage pots has since become synonymous with the perfect taper. It's pretty steep on top (great to "switch" from lead to rhythm) and musically to the end. No wonder people pay $150 or more for a single vintage potentiometer.

More than a year of R&D went into the VIPots. It included us buying and sacrificing several NOS Centralab pots from the 50s and massive analysis of their taper, torque, etc.

The VIPots are exact functional copies of the old potentiometers. The same audio taper, the same torque and US fine spline split shaft for a direct drop-in replacement. 550kOhm with 15% tolerance, putting them in the range of all the tested NOS pots."

Emerson Bumblebee ® capacitors like this Custom Paper in Oil Tone Capacitor can be found inside the tone circuits of the most sought-after classic guitars ever made. This cap offers mil-spec construction, incorporating a hermetically sealed metal tubular casing with sealed glass ends. The capacitor is comparable to vintage Sprague Vitamin Q ® Capacitors. Emerson ® Custom capacitors are constructed from the finest materials. They are the only new mil spec capacitors being made in the US. The hermetically sealed metal tubular case with sealed glass ends uses true vintage kraft paper in oil construction to provide optimal tone.
