Hello all. Bit of a long shot with this one, but thought I would ask and see what this knowledgeable community can suggest. I have an old band mate who has been teaching Salsa dance as a pro for about 20 years. He and his dance teacher wife organise a lot of music nights, and folks (and him) join in with a bunch of percussion. He’s an excellent guitarist, knows I like working on guitars, and gave me an acoustic and said ‘here’s a challenge, could you make a Cuban Tres out of that?’. He wants to move from the percussion to playing a Tres on those music nights. Yes, he could buy one but he might be crap on this, hence asking if I could cobble one together. Pretty sure that’s how they originated in the first place. There is very little on line and not much detail but I have a set of strings ( 3 pairs) and a guitar! Anybody have any advice/ experience or ideas on this one? Interesting project whatever. Cheers all.
