I am looking for string that will give me that fundamental bass sound on my G string. I've made the task more complicated because I would like to tune the G to A so I can tune in fifths (cello tuning / CGDA). Everything I have tried sounds twangy/guitarish to me. I've tried 40's and 45's. For what I am looking for the 45's are better. 50's tuned to A would be more that 60 lbs of tension which to date has frightened me off. I know the 'Jameson Set' has the G at 52 but James didn't tune to A. I've tried D'Addario XL and slow wounds, Ken Smith pressure wounds and half rounds, and GHS and Thomastik Flats. For what I am looking for half-rounds are better than rounds and flats better than half rounds but I'm still not where I want to be. I test these on passive with no attenuation on my amp. I would like the fundamental sound to be there without teaking. Obviously cutting the highs and boosting the lows and mids helps but even after I switch to active, tweak my bass and teak on my amp I'm still not getting what I am looking for. Am I beating my head/ears against the laws of physics ? (I have a relatively new Carvin LB-70 and SWR Basic Black (15" with the tube preamp).) Thanks for you thoughts and suggestions.
