Hey all, new here! I've got a cocobolo fretboard on my JDrozd fretless bass, I'm using d'addario nickel roundwounds on it. I'm noticing that the roundwounds are starting to "imprint" themselves on my bass, do I need to get my fretboard epoxied? I thought cocbolo would be hard enough for roundwounds, or is this imprint normal? thanks!
