Ghs 3120 Precision Flatwound Stainless Steel Bass Guitar Medium String SetLong revered as the "Sound of Chocolate," Precision Flats sound and feel like rock and roll history! Stainless steel ribbon wire is wound over a hex core, and polished to a velvety smooth finish. This makes a string that is deep and percussive, with a bit of throat on the attack. The top end is pulled back too, with a smoothness to the notes as you climb the fretboard. You'll sit in the mix with a deep authority, ready to anchor the band all night.
