Seagulls are nice sounding guitars. The only concern I have with the matte finish on the softer cedar tops is that they scratch so easily. (I saw some rather beat up rental Seagulls with cedar tops at one shop, I was really surprised) I was going to buy a seagull 12 string with a cedar, matte finish top; but didn't like the service at the shop (i.e I was basically ignored, while they catered to the instrument rental crowd
) I ended up at another shop and bought a Yamaha 12 string with a spruce top and gloss finish. (which I am happy with).
Unless the Yamaha is a must-have, beautifully- sounding, perfectly set-up guitar; I'd wait. Maybe, you'll come across that perfect guitar, whether it be a Seagull, Yamaha, or another brand.
