Please, help me, I am a bit confused... What is standard tuning for 6 string bass? I always thought it's just tuned in fourths, as on 5 string bass... Like (bottom-top) - B E A D G C ... But I also heard, that standard tuning is different, with major third between top two strings... Like B E A D G B .... Please, help me, I don't know which is more usual.... Thank You!
