Nice mid-tones with long sustain and volume. Comparing to my Seagull S6 Original (Dreadnaught) it has longer sustain and volume even though it is only an GC model. Probably because of the solid spruce top and mahogany back & sides. This guitar is balanced but yet can be powerful when you want it to.
Highly recommended if you have smaller hands. The 43mm nut allows for ease of playing comparing to my 46mm nut before. The action on the AR61S/ACE is great out of the box, not too high or low.
The finish on this guitar is alright, there are some glue stains but you can use a micro fiber cloth with a tiny bit of water to wipe it off. In addition, the purfling has only two stripes, not three like shown on the website.
Overall the sound of this guitar brings is on par with guitars 2x or 3x its price. Long sustain and clear mids/highs as expected from a spruce top. Would highly recommended to anyone looking for a decently affordable acoustic.
