Bright Nasty 90

Nasty 90 – (formerly Nasty 90n) this version of the P-90 Hx is the Kinman most like a regular P-90 by Gibson. Easy growl on the wound strings and sweet biting plains. Great both-on-together scooped cluck sound.

Neck position: Sounds similar to a conventional P-90 but sweeter highs (no offensive mid spikes).
Bridge position: Nasty 90 Heavy -very loud, thick, dark and syrupy sonic texture. Sounds similar to and growls and grinds like a humbucker but with better definition on the low wound strings. Huge wall of sound when played loud clean of under gain.



Bright Nasty 90 Gen-3 v2 ….. Stellar ’52 P-90 performance

There is a BIG difference between a single coil and Twin coil sidewinders and humbuckers.

The purist Kinman P-90 Hx is the only true single coil.

NEW … Bright Nasty 90 Gen-3 v2

We used to say “our Nasty 90 is the closest to a regular P-90“. Now we can say “it’s better than our early 50’s Gibson P-90 specimen”, thanks to Boss Chris’ efforts in developing our marvelous new v2 Hum Sensor and re-designing the top string sensing coil the v2 is more dynamic and has stellar highs. The redesigned Nasty 90 v2 has come of age and will wow customers with it’s stellar brilliant sizzling highs, it’s wonderful bite and gutsy, explosive dynamics from the low wound strings –and– it’s extremely fast attack response. And then there is the great both-on-together scooped c-luck sound. There is nothing second-class about this very nasty new model. Sounds far far better than the original Gen-2 Nasty 90.

More about the Gen-3 Bright Nasty 90 v2 …

  • In Neck position: Sounds identical to our specimen of a early 50’s Gibson P-90. Stellar highs with harmonic sizzle (no offensive mid spikes). Nice piano-mid-tones and it works great in the neck position.
  • In Bridge position: Focused P-90 growl n grind from the wounds, bite and harmonic richness from all strings and stellar highs from the plains.

The Bright Nasty 90 v2 works well with our Bright C&B Neck as well the 580 Alnico model in the neck position.

In the neck the Bright Nasty 90 v2 works well and balances best with another Bright Nasty 90 or a Humbucker in the bridge position.

Plastic covers sound the best (no impact) but Epiphone metal covers sound hand-over-mouth (muffled). We now sell Nickel-Silver replacement Dog-Ear covers for Epiphones.

For replacing humbuckers with a similar sound 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.

The Nasty 90 is a Zero Hum P-90 pickup. Some people will call these noiseless P-90 pickups but Kinman prefers to describe them correctly as Zero-Hum P-90 pickups. That’s because there are 2 types of noise, Hum which is cancelled in the pickup and Buzz which can only be minimized by shielding the wiring cavities (refer to >Technical >Perfect Guitar >Shielding for newer guitars

Kinman P-90 Hx can be ordered with the optional 2 wire and 5 wire Gibson Quick Connect circuit board connectors shown below. Check inside the control cavity.

Technical Stuff

The Bright Nasty 90 is a Zero Hum pickup. Some people will call these noiseless P-90 pickups but Kinman prefers to describe them correctly as Zero-Hum P-90 pickups. That’s because there are 2 types of noise, Hum which is cancelled in the pickup and Buzz which can only be minimized by shielding the wiring cavities (refer to >Technical >Perfect Guitar >Shielding for newer guitars

Upgrades: Grounded pole screws are now standard on all models as from July-2017

Pickup adjustment

As with all Kinman Gen-2 pickups these are very sensitive to height adjustment. A good starting point, so the neck and bridge pickups balance, is with the two E strings fretted at the 15th fret, adjusted as follows …

  • bridge pickup so the string-to-magnet gap is 1.25mm for both E strings
  • neck pickup so the string-to-magnet gap is 1.5mm for both E strings


When replacing an original Gibson 480 two new screw holes must be drilled in the floor of the cavity because our 580 has the mounting screws of a P-90. Cavity for original Gibson 480 is suitable, no modification required. We use Alnico-K** rod magnets, not Alnico-5 blocks as the 480 has.

Consider including our optional non-magnetic mounting plate kit, it makes install fast n easy because you don’t have to drill holes in the precise position for the pickups mounting screws in cavity floors. Do NOT use original Gibson mounting plates, being magnetic will dramatically compromise the hum cancelling ability of the P-90 Hx.


Kinman’s will bring your Epiphone to life because they achieve the maximum sonic potential of the guitar, and are easier to install than practically all other brands too because of our Easy Install Kit for f-hole guitars. Comprehensive, easy to do step-by-step instructions provided. Refer to the Overview Tab >Epiphone f-hole talk. More in Pole Spreads, next item ….


  • Bare wires for soldering.
  • Kinman connectors for plugging into a Kinman Strat, Tele or KHP-90 No-Soldering harness.
  • Gibson 2 wire & 5 wire Quick Connect circuit board connectors shown below.

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.

Cavity depth

  • No need to deepen the pickup cavity in ANY guitar that has flat bottom cavities for P-90’s. Click Install Requirements to discover requirements for pickup cavity.
  • Click this for the Install requirements for the original version, now discontinued.

Pole spreads

  • 53mm pole spread for bridge position of Stratocasters or with any bridge having saddle spread of 54+mm.
  • 50mm for Gibsons or bridges having saddle spread of 50mm ~ 54mm.
  • 47.5mm for neck position of Epiphones (NOTE: not all Epiphones have 47.5mm neck pole spread, please measure it).

  • The P-90 Hx has 2 conductor cable. 3 conductor optional.
  • Length is 380mm / 15″.
