In Stock!

A Jazzmaster with the Roar of a Dinosaur

Squier's J Mascis Jazzmaster pays homage to the indie-rocking, distortion-loving axeman behind Dinosaur Jr. This offset-waisted vintage white beauty sports a gold anodized pickguard for a touch of vintage flash. Onboard the J Mascis Jazzmaster, you'll find specs requested by J himself - an Adjusto-Matic bridge, vintage styling, and a smooth-playing satin-finished neck, to name a few. Beyond that, you'll find a duo of full-toned single-coil pickups plus the Jazzmaster's famous flexible tone controls. All in all, you'll be ready to make some noise with the Squier J Mascis Jazzmaster.

Squier J Mascis Jazzmaster Solidbody Electric Guitar at a Glance:
  • A guitar fit for a noise-rock king
  • Adds Mascis-requested mods to the already flexible Jazzmaster
A guitar fit for a noise-rock king

You'll be supremely psyched to have the Squier J Mascis Jazzmaster in your hands. This Squier pays tribute to the alt/indie rock founding father, J Mascis of Dinosaur Jr. Mascis certainly took the instrument to a new place with his feedback-drenched, distortion-laden rocking. And this new signature model pays affectionately ear-splitting homage to Mascis, giving the instrument a modern makeover for fans who've been clamoring for such a model.

Adds Mascis-requested mods to the already flexible Jazzmaster

With its vintage-inspired vintage white finish, '60s headstock, and gold anodized pickguard, the Squier J Mascis Jazzmaster features the cosmetics, pickups, and hardware specified by Mascis himself. Such cool mods include an Adjusto-Matic bridge, a slightly wider nut width, and a satin-finished neck. The Dinosaur roar comes from dual Jazzmaster single-coil pickups and the barrage of controls the Jazzmaster has always been known for - a 3-position toggle switch with volume and tone knobs and, for this model, a 2-position slide switch with volume and tone controls configured as a lead tone circuit (up) and a rhythm tone circuit (down).

Squier J Mascis Jazzmaster Solidbody Electric Guitar Features:
  • Vintage white finish
  • Basswood body
  • C-shaped maple neck
  • Rosewood fingerboard
  • 21 jumbo frets
  • 2 Jazzmaster single-coil pickups (neck and bridge)

Love my JMascis

What a great looking and great playing guitar! I've had mine a few years now. Lovee the neck. Super comfortable to play. It's like all the other reviews say. Amazing value for the price. Regarding the tremolo bar. Originally I thought there might be a problem with it at well. It would spin freely. After researching quite a bit, it turns out all you have to do to fix the problem is just push the tremolo bar in there.... Kinda hard actually. Seriously. You have to jam it in there. After that it's great. Stays in place perfectly. Zero tremelo issues since I did that. Go ahead. Jam it in there. Solves the problem. No upgrades needed at all!

You'll never go back....

Once you plug this Jazzmaster in you'll never go back to whatever else you were playing before the Squier J Mascis Jazzmaster landed in your grubby hands. Sweetwater has supplied me with years of creative fuel thanks to this guitar. Playability, tone, look,...all are on par with the $1800+ reissues that have taunted me over the years. It can be as quiet as if the amp were turned off, and as noise-addled as if Kevin Shields himself was pulling incantation from this alternative rock icon. I love everything about this guitar. The neck, the body, the masterful soapbar pick ups. And the floating tremolo? It's as if I've discovered the joy of a working tremolo bar for the first time in my 39 years. I never had to tune this guitar once. It can go from a muted jazz tone to in-your-face indie rock grit with the flick of a switch...literally. Do yourself a favor and get in touch with Sweetwater. This guitar deserves to be played, admired, and adored by you.

Best Guitar For the Money!

The Squier J Mascis Jazzmaster (or JMJM) is that rarest of things: a guitar that is ready to gig right out of the box, sounds GREAT, and doesn't break the bank. And it looks swell, too. The gold anodized pickguard is darker than it looks in the pictures and contrasts nicely with the vintage white (more like cream) paint job. Fit and finish are excellent. The neck on this guitar is a thing of beauty: jumbo frets perfectly crowned and dressed, no sharp fret ends, and a perfect C shape that fills the hand very nicely. The neck alone makes this guitar worth the money. The pickups are hotter than traditional JM pickups, and sound a bit more in the P90 range to my ears. That's not a problem. Some folks throw in more "authentic" aftermarket pickups, but I feel no need to. These sound GREAT: there's a midrange bite, but with a glassy top and nice rounded lows. Pots and switch are fine. No issues. The twang bar is wonderful, and feels wonderfully smooth. The only mods I've done to this guitar were to switch out the stock tune-o-metic style bridge (which had a rattling wire) for a roller-style TOM. It fit right on there. I also, of course, swapped out the stock strings (it ships with 10s) for a set of 11s with a wound 3rd. A 1/8 turn of the truss rod, and she was perfect. Even with pronounced use, the JMJM stays in tune. I'd recommend that anyone buying one of these plan to put on heavier strings. The "floating tremolo" system on these guitars was designed for heavy strings. 10s or lower don't exert enough tension to balance things out, and the guitar won't always return to pitch after using the bar. This is not a flaw in any way, it's the nature of the beast. As for the bridge, I find that it also helps the tuning stability to switch to the rollers. Many folks leave the bridge stock, and have no problems. I had a spare roller-style TOM laying around, so I threw it on. Ultimately, I think this guitar is the best value for your dollar on the market today. If it said "Fender" instead of "Squier," no one who's played one would blink. If it cost three times as much as it does, no one who's played one would be surprised. For the price, you cannot find a better instrument. As far as budget JMs go, these are the absolute cream of the crop. And they're certainly as good or better than the Fender-branded Classic Player or any of the others. I haven't played an American Vintage '65 JM, so I can't compare this to them, but it's a moot point. Folks who buy the $2000+ JMs would never even look at this one. Sad for them, good for us. In case it wasn't clear, I'm in love with this guitar.

Lord Almighty

I've been waiting months for this thing to come off backorder and finally received it a few days ago. I'm completely blown away. The neck is the most comfortable I've ever played in my life. The bridge pickup is nice and throaty and the neck is smooth with just the slightest bit of grit. The cosmetics are flawless. It sounds so much better in person than in the few video reviews floating around YouTube that instead of being a back-up I can already tell this is going to replace my Highway One Strat as my main guitar. I expected a nice guitar for the money. I didn't expect this. If you're even slightly considering this guitar, buy it now.
