on my carvin, which is a fretless, i have on Daddario Chromes, high finish ribbon wound. now these worked fine for a while, never loved the tone they gave but i could deal with it. but now, my guitarist tunes down to some odd tuning with his gibson, so now with my carvin i need to match his tuning. so now my tone is just horrible. it sounds all muddy and whatever i do to my bass or amp it doesnt sound good. i am thinking it has to be the strings and how de-tuned they are. so is there a brand to sting that wont tear up my fretboard but wont sound to muddy being tuned so low?
