hmmm...no takers, eh?
well, i used to do
at the mambo inn, kind of like how grant green did it on
the latin bit (great disc, get it if you don't have it).
i comped using dotted quarter, dotted quarter, eighth pattern. you can mix that up with the typical
son clave pattern, won't sound too bad:
latin american guitar styles by kent murdick is a good resource. he gives a fingerstyle comp for fast mambo with a two measure pattern, bass (thumb) on the half notes with the second measure bass notes an eighth note early (like tumbao). the rest of the chord (i-m-a fingers) are on beat two 1st ms, 'and' of 3, 1st ms; 'and' of 1, 2nd ms, 'and' of 3 & 'and' of 4, second ms.
this looks interesting:
