Centralab™ Potentiometers

The Holy Grail of Potentiometers is back (Afterv40 Years).

"In the late 50s (Golden Age of Guitars) Gibson (and others) used potentiometers  by US maker Centralab ™.” The audio taper of these “Holy Grail” of potentiometers have 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 to $600 or more for a single vintage potentiometer.

After 40 Years Centralab™ has agreed to put these back into producton. They are 550K Audio. 24 Fine Spline.™



Yellow Varnish Spaghetti Tubing


These Caps are the PIO (Paper in Oil) and the tones are similar to a Bumblebee and Vitamin Q. The tones are unbelievable. This is a Harness for the Very Serious Guitar Player who is a Tone Chaser.

The oil used and the construction of the Capacitors are to our demanding specifications. .022 uF is common value in Gibson and Gibson-style guitars using Humbucker or P90 pickups. A very nice upgrade.
