Geez I cant wait till my fretless arrives... My hands are a state because i'm allergic to nickel and my rockbass has... nickel frets. I use Rotosound swingbass strings and these are apparently 100% nickel free, so I can only assume its the frets that do it. Its only my left hand too... Does anyone else suffer from this? And if so do you have any tips to help eliviate the problem?
