The 60th Anniversary ’58 was an American-made model that came out in 2018, featuring an ash body and 2-color sunburst finish. (Not to be confused with the 60th Anniversary Classic Jazzmaster, which also came out that year. The 60th Anniversary Classic was a Mexico-made guitar with different colors, specs and pickups.)
Fender’s serial number lookup website says the pickups in this model are Pure Vintage '65 Single-Coil Jazzmaster pickups. Although they changed the pickup covers to black, to match the earliest 1958 models.
The lead circuit pots in this guitar are both 1Meg. The rhythm circuit volume pot is 1Meg, and tone pot is 50K. This is what Fender used on the original run of the Jazzmaster. The 50K tone pot in the rhythm circuit, which is darker sounding than the lead circuit, is like only using the 0 through 2 settings of the lead tone pot.
250K and 500K pots are the most common pots. Conventional wisdom is to use 250K for single coil pickups and 500K for humbuckers. A lower value pot rolls off more treble, so 250K is commonly used on single coils and 500K is commonly used on humbuckers (which are darker than single coils). 1Meg pots are usually considered very bright and trebly. Different pots can affect bass, punchiness and other things, so people will have different opinions which pots work for certain pickups or achieve a certain tone.
The orange capacitor on the lead tone pot is 0.030uF. The orange capacitor on the rhythm circuit is 0.020uF. This matches the schematic for an original Jazzmaster on guitarHQ.com.
Most Fenders usually use a 0.046uF cap, and Gibsons usually use a 0.022uF cap. The higher value on a cap, the wider the frequencies that are rolled off when you turn down the tone knob. A lower value cap only rolls off the highest frequencies when you turn down the tone knob.
The 60th Anniversary ’58 Jazzmaster is very bright and trebly sounding, and can get close to ice picky like some Telecasters. If you watch YouTube videos featuring this model, you can hear the brightness. The brightness can be easily dealt with by changing out the pots. Although some people prefer the 1Meg pot to stay “vintage,” or they feel lower value pots affect the unique sound of the Jazzmaster. For now, with this guitar (and with bright Telecasters), I usually turn the volume knob a notch, maybe about 1/8 of a turn down from 10, to tame the harshness on the top end. I usually find that sounds better than turning down the tone knob a notch. (Lollar Guitars’ website mentions they find using a 500K pot to sound like turning a 1Meg pot down to 7 or 8 on the volume knob.)
Fender has used different pickups, pots and caps on more recent Jazzmaster models. For example, the American Vintage II 1966 Jazzmaster uses 1Meg pots in the lead circuit. But I saw a schematic on this forum showing the American Professional II Jazzmaster using 500K pots and a 0.022uF capacitor in the lead circuit.
