Multi-Voice, Multi-Talented

Nowhere are the intrinsic benefits of Fluence Technology more up front and apparent then when applied to the P90.

Unlike stacked “humbucker” P90 variants which can actually aggravate certain problems while curing others, the noise, the acoustic feedback, the hum, the inductance issues caused by guitar cables, amp and effect inputs… with Fluence, all of it is eliminated, leaving pure, unadulterated, Multi-Voice tone.

The Gristlemaster Magic

From growling, explosive humbucking tones to crystal clear single-coil sounds, Fluence Multi-Voice technology allows you to harness the full sonic potential of your guitar. Toggle between three musically complementary voices, or combine a Fluence alnico at the neck position with a Fluence ceramic in the bridge position for double the voices.
