Do not trust too much to his name. This product will not really "play faster" (although) it is satisfied just to protect and restore your strings slightly. And for bass, with their big rods and sets that cost an arm, it is more than recommended! 1) Fast Fret cleans the strings. 2) makes contact with round nets more enjoyable. I regularly blisters on his left hand with my Rotosound after applying Fast Freight, the contact is much less painful ... and fewer bulbs generator 3) The product makes some brilliance to the sound. Unlike other reviews, I noticed a marked improvement playing slap. 4) Corrosion is more controlled (and for players who sweat is good news). 5) reduces noise frets and finger slippage. In short, a product that is not at all "can" and avoid bassists to ruin by changing too often their cords. There is no miracle, but what it does it does well.
