Chromatic Node weights for CX12 and SCX harmonicas

I have been making and fitting these nodal weights into 12 hole chromatics for a while now as part of my chromatic servicing. A customer asked me if he could buy them on their own and fit them himself as he was from overseas and the harp didn't need servicing. So I thought why not. So here is what they are all about. You can get them from my website and fit them yourself...any questions just ask. thanks john
