I'm a singer/songwriter, and have been playing chords for over 10 years now. While trying out th Seagull S6 I was gonna buy, I kept walking back to the Martin just to do comparisons. You know what, the seagull has an awesome smooth/warm tone, comparable to the Martin. I love the Seagull S6, and my next guitar will probably be the Seagull Mosaic with the solid top and bottom for only $700.00.
If you don' think a Seagull sounds good, you're tone deaf.
