It provides a convenient way for players to navigate a space between the temperate and traditional character called .047uf, and its slightly more dramatic and swampier sibling called .1uf. More specifically, the .047uf allows remnants of the high end to beam through; and if perceived by the player as not so tangible.

In the case of the .1uf cap, it is the hand that yanks the Thing just beneath the bright-bound surface. Everything capitulates an electric, light-drowned mud. Dive toward the murk.

Technical Details:

  1. 250k Push-Pull Potentiometer

  2. .047uf capacitor as baseline (pushed in)

  3. .1uf capacitor on top of baseline (pulled)

  4. The rest: solder, wire, and simplicity.

We offer a full fitting service including routing for new/change of pickups, more information HERE.
