Prewired Jazzmaster - JM-180 Two Zone Wiring
JM180 2-Zone Jazzmaster® Wiring
Introducing a totally cool mod for you Jazzmaster® that requires absolutely no visual changes to your instrument. Your pickup will have 2 modes: normal gain and high gain! No batteries, no preamps, just 2 version of a pickup in one. Curtis Novak's amazing JM180 pickup is built on his very popular JM-90 platform, but takes this great pickup to a whole new level. Like with his JM-90 this will fit in a standard Jazzmaster pickup route.
Here's the deal. I can't tell you how many serious Jazzmaster players have told me they NEVER use the upper rhythm, it is just too dark, or it sounds like someone stuffed cotton in your ears... So Curt got the idea of this tapped JM pickup and we worked together to redesign the wiring for the upper rhythm circuit converting it into a high gain lead circuit with its own separate volume and tone. So when you slide the switch to the upper circuit you will get the Full JM-180. Curt came up with the name JM-180 because it is 2 full JM-90's in one, but also it does a complete 180 on the dark rhythm circuit making it a over driven lead circuit, without the need of an overdrive pedal.
Please note we are using special pots and caps for this circuit not available from the usual guitar parts suppliers. Curt and I agreed to get the best tone out of the JM180 pickup, we should not use the standard 1M and 50K pots normally found in the upper circuit. After much testing we both agreed the optimal value would be 500K audio taper for the volume, and 500K linear taper for the tone but we needed these pots to fit the upper circuit's mounting bracket and have a solid shaft to take the roller knobs. Luckily we were able to score the perfect pots that have solid shafts are are the exact same size as your traditional jazzmaster mini-pots!!
Special Cap for the famous Clapton Woman Tone!
We are using a special value orange drop capacitor that will give you that highly sought after and famous Clapton Woman Tone that works perfectly for the high-gain circuit. The cap value is lower than normal. 022 uf and will enable you to rotate your roller tone knob fully counterclockwise and it will not sound muddy, but instead will give you a really creamy distortion when pushing the amp to overdrive. Please note the upper circuit is totally vintage and still uses a .033 uf capacitor.
Just like all our other assemblies, these prewired Jazzmaster® assemblies use only the finest electronic components, and are even 'period correct' with regards to the color coding of the vintage style cloth wire. All components are treated with Caig Deoxit for long trouble free use. They feature our custom made copper shields, only available at Rothstein Guitars. Fair warning, these will not be inexpensive but they will be of the highest quality you can find and worth every penny.
Enough with talking about it Here are 2 different sound files switching between the JM-90 and the JM-180. The first part is the JM-90 coil tap on the lower circuit, the second is the full JM-180 on the upper circuit.

SBE Orange Drop capacitors will be used at no extra charge, or for an upcharge you may select between Musicaps, and the ultra high quality V-Cap TFTF Teflon Film and Foil capacitors. The price will vary depending upon which capacitor you select. NOTE: If selecting either VCAP or Musicaps, that will be used in the lead circuit only. The rhythm circuit will have an Orange Drop. Read about capacitor choices here.
A volume kit (also know as a "treble retention circuit" or "high-pass filter") is used to prevent the loss of highs associated with lowering the volume on your guitar. We use a 1000 pf Mallory 150 Series Metalized Polyester Tubular capacitor in parallel with a 150K resistor.
We offer pickguards in white, mint, tortoise (** see note below) and genuine gold anodized which look killer. Here are a couple of pictures of our gold anodized pickguards photographed with different lighting.
A Note About Fit
The pickguards we carry are manufactured by Fender or WD Music, both of which are patterned after USA Jazzmasters, and will therefore drop right into any USA Fender Jazzmaster, however we now carry both the import and USA versions of the tortoise pickguard since it by far the most popular color choice. Upon special request, we can special order an import pickguard in another color such as white pearl. Please note the difference between between the pattern of the import and USA pickguards is relatively minor, however there are some differences with regards to color.
The image below will show the color variations between the USA vs the import tortoise pickguard. You can click on the image to see a larger version.
* IMPORTANT NOTE ABOUT CELLULOID PICKUARDS (this applies to Tortoise Pickguards)
** Tortoise pickguards are made of Celluloid like you will see on vintage Fender guitars. This is the GENUINE stuff. Please be aware that celluloid is very flammable, so please keep it away from flames. Celluloid is a solvent based plastic and it tends to shrink over the years. Many vintage Fender guitars are plagued with this phenomenon. Very often the material cups slightly, so that when placed on a flat surface its edges may be raised 1/4" to 1/2" above the surface. Even if they're cupped when they come out of the package, they can easily be screwed flat onto the guitar.
We are the only company offering pre-wired harnesses with very high quality, noise canceling, THICK copper shielding. Read more about our shields here.
KNOBS AND COVERS
Available in white, black and cream.
The copper shield will be embossed with our logo as a method of branding and authenticating our wiring.
