Tone? I go for about the opposite of what most modern players are getting these days. I have no growl, no bite, no razor edge in the high end...I use flats, warm buttery smooth tone, no loss of high end due to the series one bass, on the contrary very distinct high end separate from my low signal. to me, the high end when playing in the upper registers is what really makes the most profound difference to my ears when comparing bass tones. Most basses are very capable of producing thundering low end, but to me lack or compromise the upper frequencies. I also scoop the upper mids from my GKRB1001 II amp while leaving all other EQ flat.
I play rock music mostly.
my tone while not for everyone is very satisfying to me.
