I have two Warrior basses I play and use the same GK 700rb head. I use a SWR 4x10 with one and a Ampeg 6x10 with the other. I'm not totally satisfied with my tones I'm getting with either bass. Both cabs have tweeters but I generally turn them down unless playing outside. I know a lot of good basses use the Bart's so I guess my question is more about my choice of 10 inch speakers. If I were to go with 12's or 15's, would it change a lot. I use Ernie Ball slinky light gauge either .40-.125 or .45-.130 strings. Any suggestions? I would describe my current tones as a little too modern and less vintage sounding.
