I recently got a guitar cleaning and conditioning set to keep my guitar in good shape, but just as I'm preparing to apply one of the bottles to the fretboard I see a notice on it, saying 'not for use on maple fingerboards'. I've an Ibanez RG3120 now, of which I know pretty much all the details in terms of body wood and so on, but I've no idea what sort of wood the fretboard is made of. I checked the Ibanez site and also had a look into the catalogue but no luck I'm afraid. Can anyone help?
