Remo M6 S675 Fd 6 75 Inch Fiberskyn Weatherking Survey These "cueros" are the bees knees! They sound loud with little effort. Just tune them and off you go to the rhumba! This heads made a lot of difference on my Aspire Santana Bongos. Now I can get higher pitched crisp tones with out killing my fingers. These sounds seem more appropriate for modern bachata and salsa music, so an intermediate player like me can feel more music coming out of the instrument. But I'm sure some advanced players may miss the warmer tones from the original cow skin heads. Excelente producto!!todo de acuerdo a las especificaciones del vendedor!!sin contratiempos en la entrega!rapido envio y entrega antes de lo previsto!! At first, I was really hesitant to trade the natural feel and sound of tradition rawhide skins. I ordered this Remo online and I have to say I am impressed. The feel of the skin may feel a bit akward at first for those used to the natural one, but it is nota major issue. You get used to it. Now, onto the crucial aspect which is sound. Sound wise, the skin is pretty much similar tothe natural one. Although you have to rememberthis is a 3 3/4 inch head, meaning that the high pitch is harder to distinguish from the rawhide since most bongo heads are tuned simirlarly. In short, it sounds great and would reccomend it. I would have give an update on the 8 inch one if I ever need it.
