VIP 550k Short Shaft Audio Pots Centralab Specs (The Holy Grail of Guitar Potentiometers)
Yellow Varnish Spaghetti Tubing
"Everyone in the know knows that the magic of the "old" tone does not only come from somewhat magical pickups. The electronic components are just as important -- especially the potentiometers used back in the golden age of guitar making.
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."Capacitors
