I tried D'Addario Chromes last year. I wanted Flats with a healthy tension on the B since I have a 34" bass. The Low B had to much of a dull thud sound. I went back to GHS Boomers roundwound. I recently bought GHS Precision Flats, but the store only had E - G. I put the old D'Addario Low B back on. Again dull thud, so I put a Low B GHS Boomer back on the B. Now I have one groundwound and flatwounds on E - G. I like this approach for now. Does anyone make a Low B that does not have a dull thud sound? Should I try a TI flats that I hear people like but is floppy. Does the TI have a dull thud sound? I play real hard at times, so I figured I need tension.
