Nasty 90 Heavy

Availability: Out of stock

makes Humbuckers obsolete!


Nasty 90 Heavy (Formerly the Nasty 90b) ; in bridge position: very loud (highest output), thick, dark and syrupy sonic texture.  Sounds similar to and growls and grinds like a humbucker but with better definition and clarity on the low wound strings and sweet sounding plain strings that are not overly trebly/ice-picky like most humbuckers.  Huge wall of sound when played loud clean of under gain. 

Recommended primarily for bridge position regardless of volume.  A Nasty 90 in the neck position works well and balances with it.  

Recommended for the neck position only when a regular humbucker is suitable and then delivers better definition than most  humbuckers.

For replacing humbuckers also look at our P90-Bucker in the Humbucker section. 

You will have a lot of fun, enjoyment and satisfaction exploring the extended sonic dimensions of these remarkably advanced pickups.



  • Bare wires for soldering.

Output Polarity: 

  • in-phase with Gibson and Copy humbuckers
  • in-phase with all other Kinman pickups
  • opposite phase to Fender Strat
  • Fender pickups have opposite output polarity so consider Kinman's Strat models which have same output polarity.

Pot & Capacitor values

  • Best with 500k Ohm for Volume.  Many Gibson's have 300k which makes a darker, less dynamic sound.
  • Normal Tone pot is 500k however to maximize clarity use a No-Load or alternatively a 1 Meg Ohm tone pot.
  • Normal tone cap value of 0.022µF in 63 ~ 100 volt Polyester.  Smaller value lessen the severity of Treble cut, higher values increase it.

Pole spreads

  • 50mm for Gibsons or bridges having saddle spread of 50mm ~ 54mm.

Hook-up cable

  • The P-90 Hx has 2 conductor cable.  
  • Length is 380mm / 15".

Mounting hardware

  • 2 Long mounting screws.
  • 2 Silicon Rubber tube springs.
  • handy drill guide template for positioning the screw holes in the virgin floor of the pickup cavity of a project guitar or guitars with freshly deepened cavities.
  • Bracket for mounting under Dog-Ear covers in Arch-top f-hole guitars available as optional extra.
