what flatwound has the rich tone and playability of Thomastik flats but has more girth? Loving the rich mid tone and they record really well. But I miss the weight down low and reaching for the bass knob doesn’t cut it for me. Even just a little more girth would do it. Maybe it can’t be had from those string gauges. I’ve played black 105 Sadowskys and 105 and 109 Labellas extensively over the years, and briefly GHS 55-105 flats. This is for a ‘66 P bass. Thanks in advance for your comments!
