D'Addario EJ22 Jazz Medium (.013–.056): the wound-third electric standard

D'Addario EJ22 is the canonical XL Nickel Round Wound Jazz Medium electric set, .013 to .056, with a wound .026 G string instead of the plain G that ships on every standard rock electric set. The wound third is the defining feature: it tightens intonation, evens out tonal stepping across the lower four strings, and produces the dense chord-melody tone that the post-war jazz electric guitar sound was engineered around.

Made in D'Addario's Farmingdale, New York facility. Same XL Nickel material and hex-core construction as the EXL line, just with the heavier gauges and the wound G that defines the jazz-medium spec.

A wound G string is the single most consequential gauge choice that distinguishes jazz electric from rock electric. Three things shift when the G goes from plain .017 to wound .026:

Intonation tightens. A plain steel string at .017 thickness has measurably more pitch drift at the upper fretboard than a wound .026 string at the same pitch. Mid-century archtop builders (Gibson, D'Angelico, Stromberg) designed their bridge compensation, fret slotting, and scale lengths around wound-third specs because the additional intonation accuracy was audible in chord work above the 12th fret.

Tonal stepping evens out. On a plain-G set, the transition from the wound D string (.026 to .032 typically) to the plain G (.017 to .020) creates a noticeable tonal step: the wound D has a fundamental-rich tone with overtone content from the wrap, while the plain G has a cleaner, brighter, more harmonic tone with less low-mid content. On a wound-G set, that step is smoothed: D and G share the same wrap construction, so they share the same tonal profile, and chord voicings across the lower four strings sound uniform.

Feel changes for fingerstyle. A wound G has a softer, more compliant surface texture under a fingertip than a plain G. For thumb-and-fingers chord-melody, fingerstyle bass-note + chord work, and archtop comping, the wound G feels more like the rest of the lower strings and less like a separate instrument family. Players who play primarily with picks notice this less; players who play primarily with their fingers notice it immediately.

The wound G has one big drawback: it doesn't bend cleanly. A .026 wound G at concert pitch has roughly 35 to 40% more tension than a .017 plain G, and the wrap material doesn't slide under the fretting fingertip the way a plain string does. Bending a whole step on a wound .026 G is physically possible but produces audible wrap-string buzz and uneven pitch curve that ruins the bend's musical effect.

Genres where bending the G is technical core (blues, rock, country, modern pop) require a plain G. Players in those genres reach for Regular Slinky, EXL110, Boomers GBL, or any standard rock set with the .017 plain G. Switching to EJ22 for those genres is technically possible but musically wrong.

Jazz electric guitarists on archtops (Gibson L-5, L-4, ES-175, L-7, L-50; Epiphone Emperor, Sheraton; D'Angelico EXL-1; Eastman AR series) and semi-hollows (Gibson ES-335, ES-339, ES-345). Rockabilly players on Gretsch 6120 / White Falcon / Country Gentleman. Western swing rhythm guitarists. Country chord-melody players whose tradition descends from the wound-third pre-1970s era. Anyone whose chord-melody and rhythm comping is the technical core of their playing and bending is incidental.

Modern rock, blues, country, and pop where bending the G string is technical core. Solid-body Strat / Tele players whose music is bend-heavy (the heavier gauges also raise neck tension by 25 to 35 lbs vs. a Regular Light set, which can pull the truss rod tighter than the guitar was set up for). Floating-bridge electrics adjusted for Light or Regular gauges. Vintage instruments with non-adjustable truss rods or thin necks where the additional tension is a structural concern.

If your tradition is jazz, rockabilly, Western swing, or any genre where wound-third heavy-gauge electric is the working-canon setup, EJ22 is the canonical XL Nickel Round Wound choice in that lane. The wound .026 G is the defining feature, and the heavy .013 to .056 gauge profile is the gauge mid-century archtops were designed around. Pick this set when the music is chord-melody and rhythm comping, when the guitar is an archtop or semi-hollow built for it, and when bending the G isn't part of the playing vocabulary. For the flatwound version of the same gauge, step to ECG24 Chromes.

Specific named EJ22 endorsements are sparse in primary-source documentation. D'Addario's published artist roster includes many jazz electric guitarists (John Scofield, Mike Stern, John McLaughlin, Eric Johnson, among others), but most of those players use custom-spec D'Addario sets rather than stock EJ22:

• John Scofield plays D'Addario .013 to .052 with a plain .022 G string he can bend, per his Premier Guitar rig rundown. Heavy gauge, but plain G, not wound. Adjacent lane.
• Mike Stern uses a custom D'Addario set in the .011 to .038 range, lighter than EJ22, plain G.
• Eric Johnson moved from GHS to D'Addario circa 2017, uses .010 to .050 custom with plain .018 G.
• John McLaughlin has used D'Addario XL .010 light gauge for solo work.

The EJ22 lane is a working-canon spec rather than a famous-player signature: jazz session players, archtop owners, rockabilly rhythm guitarists, and country chord-melody players reach for it as a tool for the rig rather than as a tone-imitation choice. The .013-.056 wound-third gauge is the canonical jazz electric setup; the specific brand-and-set choice within that lane is editorial preference.
