Hi ! i'll ask some favor because i just can't make my choice. I've played the bass when i was a teenage in several numetal/hxc bands than i turn to electronic music. But now i listening a lot of metal like i used to so i want to put some metal in my music. I want to keep it focused in the low frequency and with hard synthetic rythm in your face My problem is a just can't choose between extended range guitar (8 strings) or bass guitar as the main instrument with guitar i could probably make more complex melodical stuff and dissonant chord i like (dimished 2nd) but will probably need to had a synthetic bass beneath to have my focus on low frequency : do you think a 8 strings could work without bass ? With bass it'll be allready in the good frequency range and i think i could play tracks faster. i've allready play the bass so i think i could learn back quickly. but my problem is do you think a bass with some effect could fill up the spectrum completetly ? i just don't know it's really hard to make a choice ... feel free to comment !
