Fishman Fluence Phase Inverter Kit

Add out-of-phase capability to your Fluence pickups with a Fishman Fluence Phase Inverter. Includes adjustable trim pot so you can dial in the perfect tone.

Fishman's Phase Inverter push/pull control allows convenient access to the out-of-phase tone, and includes a hidden set-and-forget potentiometer that also allows you to preset a "Peter Green" blended sound even with only one volume wiring!

For years, the sound of two pickups out-of-phase has been a staple tone for certain players, such as Peter Green and Jimmy Page, but it's a very distinctive sound. For this reason, many players want it available on a switch so they can go back to normal. In addition, the out-of-phase sound is so sensitive to the pickup levels and balance that Fishman included a trim pot for the phase inverted pickup that is capable of lowering the volume or raising it above unity gain so that you can preset the exact sound.

There are also players who want to combine different brands of pickups that are naturally out-of-phase without the wiring capabilities to reverse them, but the player wishes they were in phase. This can be used to correct that, and allow the pickups to be blended in phase.

Check your existing pot shafts and knobs before you order! Fishman offers 4 variations of this product with different dimensions and configurations - make sure you order the proper one for your instrument!

Most press-on knobs are made to fit a coarse 18-tooth knurled shaft potentiometer. Some Gibson-style knobs are available in both coarse 18-spline and fine 24-spline. If you currently have 24-spline knobs you may need replacement knobs designed for 18-spline shafts. read more For many screw-tightening knobs, the 6mm solid (plain) shaft is the correct option. If you are unsure of which pot you are replacing, please research and confirm before you order.
