The Fatfinger is an effective and natural sustain enhancer when clamped to the headstock of your bass guitar. Tune out dead spots found on almost every bass by simply changing the point of contact to the headstock. The Fatfinger installs in seconds and gives instant and amazing results. . . even for the most hardened tonal skeptic! The Science. . . The physics of the Fatfinger Bass Sustain Enhancer are simple: by effectively adding 2 to 3 times more mass to the "weak" end of any stringed instrument, the strings ring out longer, louder, and with more balance. The increased sustain is immediately apparent, but improved balance is the ultimate reward. The Fatfinger's mass lowers the frequency of the harmonic imperfections, or nodes, of any stringed instrument. These dead spots are moved below the audible range, and so are effectively eliminated! It's an incredible "fix" for that Fender Jazz Bass with the "disappearing C note" syndrome! Made of chrome plated bell brass for much mass. And that little chrome finger on the headstock of your guitar will make your friends swoon with envy! The Fatfinger cannot damage your instrument in any way.
