I watched this video and I like the way he plays chords. He sounds good to my ears when he plays chords. There is also short moment when he plays single note melody and this sounds terrible to me. Is this true that cheaper guitars sound acceptable when one plays chords but they sound bad when one plays solos ? If yes, why is it like that ?
That first example of rhythm playing was actually awesome but the way he played minor swing it was almost like a completely different person. His single notes didn't sound that great because he played right over the soundhole so he couldn't get much attack in his tone. The guitar sounds pretty nice to me. Unless the guitar is unplayable POS, a big part of the final sound is in the technique.
To paraphrase VW slogan line "players wanted".
The DG cut way more, but the Altamira had a substantial amount of low and mid end response as well as more overall volume in general. The single note lines were easier to keep at a consistent, healthy volume. However, I don't think the Gitane isn't a quality instrument- it may just be harder to work in certain situations such as playing lead, especially if you don't have correct technique. I find I have to work just a little harder to keep the volume up, but if you have an attentive rhythm player, then hopefully they would be conscious of this and bring their total volume down in order to support you.
Here's a recording with the Gitane DG255, playing both rhythm and lead. I think it sounds decent in both aspects!
