I had a set of DR Sunbeam's on my Jazz5 for a long time. Without going into the nitty gritty, I ordered a new set of Sunbeams, 45-125 and put them on a month ago. As I've been doing some recording lately I had tested my basses to see which one I liked recording with the most and would have thought that the Jazz5 would be a contender if not the winner. I just didn't like the way it sounded with these strings, even though a month old. Even in my mind, while practicing, I remembered liking the sound of the Sunbeams that I took off. There have been sounding so much different, though the only difference is the low B, where I tried the 125 rather than 130. But that isn't it. So last night I put the old Sunbeams back on and am more comfortable with that sound. They were on the bass for months before putting new strings, but I am more comfortable with the sound, at least for the type of music I've been called on to do. As a side note, one of the things that pushed me to try a new set was that with the 45-130's, the low B, at least after time, was significantly louder than the others. As a stop-gap before getting new strings I swapped out that low B for a D'Addario NYXL taper-core 130 which seemed a better balance. Upon a conversation with DR, we decided that I should try 45-125's. They balance very well on this bass, but I guess I just needed a more broken in sound. The new set will go back in the drawer until the old strings totaly bite the dust. Has anyone else had a similar experience?
