The guiro that's used for bachata is usually a metal one, a large, rough tin cylinder not wood. It can be scraped with a stick or tapped on for a lot of other effects. Here's a link to see it:http://www.youtube.com/watch?v=-fCraMMQqx4. There's a good view of it at 0:58. I found that the cabasa samples on SampleTank are a reasonable substitute. Now that this thread is bumped, has anybody had experience getting the lead guitar sound?
