The Artimúsica RJ80S is a cavaquinho rajão, with five strings instead of the usual four, he tunes A-E-C-G-D, from the 1st to the 5th string, but with the 3rd string being the lowest, which gives it a very characteristic sound. The top is made of solid spruce and the bottom and sides are made of walnut, also solid. This combination gives it a brilliant sound and greater resistance and durability. The neck is in mahogany, and the fingerboard is in panga panga, two woods that contrast very well with the tones of the body. The head has a very modern and interesting asymmetric design, boasting five tuning machines arranged three / two. The glossy finish highlights the wood grain while protecting it. The Artimúsica RJ80S also has a round mouth, with simple decoration, but with very good taste. It is a very well built instrument, with an impeccable sound. Artimúsica RJ80S is manufactured in Portugal, by a national brand.
