I don't mean the brand, I mean, B? E? A? D? G? ...C? I think every decent bassist has something he could call a 'favorite string', which he likes the most because of timbre, or ease of playing, or something The question might seem awkward, but I think it'd be an interesting thing to discuss, especially when explained why. Aside from position and 'what the song really needs', we all have preferences on 'which string to play this note on?' if we have to choose. To me it's mostly D (60 in my case) - it is just perfect on my fingers and the position it is on my jazz is very delightful to play. Yours?
