My bass is tuned down to D-G-C-F when playing with my current band. I have the strings-hitting-the-fretboard problem when playing fast and when I raise them it's really hard for me to play as I'm not an experienced bass player. I've seen that the DigiTech BNX3 has some effect called the pitch shifter. With that, can I tune my bass to standart setting and have the output sound 2 steps down? If I can, will the sound be good and natural? If not, what do you advise me to do?
