Seagull's quest for tone gives you a better playing and sounding guitar

Robert Godin, owner of Seagull Guitars, has never been satisfied with good enough. His tireless search for the better guitar has created quite a few innovations that go into every guitar model that Seagull makes. Every Coastline S12 Cedar QI's top is pressure tested for rigidity and stiffness to ensure maximum harmonic vibration. The unique compound-curved top adds structural integrity to the guitar and allows for thinner bracing. Take it from the Sweetwater crew - the Coastline S12 Cedar QI acoustic will give you years of great performance.

Innovative neck construction and mounting delivers killer playability and tone

The attention and care given to each Seagull shows in their looks, playability, and tone. Seagull has also taken extra care to ensure that the Coastline S12 Cedar QI's neck helps create an amazing guitar experience. An acoustic guitar's neck is more than just a fretboard used for playing, it also creates the guitar's tone. Seagull's Integrated Set Neck gives your guitar the sound you want and the stability you need in a performing guitar. This system provides stable and consistent action that also reduces warping and twisting. Thanks to this integrated system, the Coastline S12 Cedar QI's neck pitch is perfectly set. If it's too far forward the instrument will sound muddy, or if it's too far back the guitar will sound tinny. Seagull's design assures optimized sound and playability with these and other innovations found in the entire Seagull line.

Handcrafted in Canada for more than a quarter of a century

For over 25 years, Seagull guitars have been handcrafted in the small village of La Patrie in eastern Quebec. About half of the population works creating these exquisite guitars. All of the guitars in the Seagull line are made in Canada from the S6 Original models to the Maritime models to the top-of-the-line Artist series guitar. Most of the tonewoods are also harvested from Canadian forests. You'll love the attention to detail, the quality tonewoods, and Seagull's commitment to make the best guitar possible. Grab a Seagull Coastline S12 Cedar QI and experience the difference.

Seagull Coastline S12 Cedar QI 12-string Acoustic-electric Guitar Features:
  • Pressure tested solid cedar top offers superior tone, projection, and response
  • Laminated wild cherry back and sides deliver a detailed tone between warm mahogany and bright maple
  • Modified dreadnought body shape cuts unwanted boominess making it great for recording and live shows
  • Quantum I electronics deliver great plugged-in tone via an undersaddle pickup
  • Integrated set neck offers tuning and playing stability and eliminates twisting and warping
  • Tapered headstock gives you a straighter pull, better tuning, and less stress, especially when using altered tunings
  • Tusq nut and compensated saddle offer a sound similar to bone but with more harmonics
  • Thin, custom polished finish lets the guitar vibrate more freely
  • Dual-function truss rods assure the perfect neck alignment and relief
  • Handcrafted in Canada

Great guitar for the price

A couple of months ago I had purchased the Coastline S12 Cedar Ql acoustic guitar and was pleasantly surprised by its quality and sound right out of the box. It has great action and plugged in it sounds great. I play mostly 6 string guitars and wanted a good yet affordable guitar and this fits the bill. I have gifted this guitar to my pastor because the one problem for my small hands was the neck width. He has bigger hands and he is absolutely blown away by this guitar. My professional rep at Sweetwater is Scott and he is as accessible, friendly, passionate and professional as they come. I highly recommend this product and this company.

Best guitar for the price

You simply can't find a better built, nicer sounding guitar at this price point than the Seagull. The S12 Coastline is an excellent example of this. This guitar blows me away! I have a Martin that doesn't perform this well.
Music background: Played guitar since 1964

Most musical acoustic I've ever owned

I'm simply amazed at the way this instrument sounds and plays. Its complex harmonics, excellent lows and highs simply ring out. I've owned a number of acoustics over the decades and this one surpasses instruments that sell in the 4 figure range. VERY easy to play barre chords and unplugged it's sweet and soothing or aggressive depending on my attack. Plugged in, I'm amazed at the ability of the electronics to reproduce the acoustic tones of this well built instrument. Highly recommended!!


I have owned over a hundred guitars in my life and never would even look at a seagull because in my eyes it wasn't a big name brand but as I was playing some Martin 12 strings and Taylor 12 strings was not all that impressed with the ones I was playing for the money they wanted for them, so the salesman handed me and S 12 seagull, with the first strum I was impressed with how bright and clean and loud it sounded like an 212 guild 12 string guitar I am sorry I sold I was impressed that it was made in Canada and then it was a solid wood guitar for 500 bucks,with Foam soft case,you'd never get that with a guitar made in the USA don't know how they're doing it , keep up the good work Seagal you hosers are making a great guitarfor a great price
Music background: playing guitar since I was 10 now I'm 61

Seagull Coastline S12 Cedar

I'm really pleased with my Seagull 12 string. The combination of woods used in its construction project a clear crisp natural sound. Nicely weight balanced and not terribly heavy. The electronics are very good ; the guitar sounds marvelous through a pair of Fishman Mini amps. Thanks are extended for the modern integral tuner. This eradicates the difficulties involved with proper tuning of a 12-string guitar. I like the soft satin finish. It is very attractive and comfortable to hold and play. I am not crazy about the gig bag (purchased separately) and would have preferred a hard case. Overall, a wonderful instrument with superb pre and post sale follow-up from Brad at Sweetwater.
