Hi, Ive recently bought a beautiful 30-year-old Roger Dawson bass with a great pedigree (London Symphony Orchestra, BBC Concert Orchestra etc....) but something strange is going on. Im finding that the harmonic on the G string is much sharper than the open string itself. Ive changed string a number of times ( Im currently using a Flexicor G) The bass has a new bridge and has been set up in the last month or so. All the other strings harmonics are totally in tune with their respective open string. Using a tuner, which I often do, the open string seems to be about 2-3 cents flatter than the harmonic. The next thing When I tune up with the tuner using harmonics, the bass feels nicely in tune and very comfortable. When I tune up using open strings, notes played on the G string are consistently sharp. Clearly Im going to waste no time in getting the bass looked at, but I was wondering whether anyone had any experience of this, or indeed might be able to suggest a reason/solution? Thanks.
