Okay, so in one of the songs my band and I play, everything cuts and I have to play a bass riff as a solo part. I noticed that when I play fast notes, all of them just kinda fuse together I guess you could say. I tried tweeking the EQ but that didn't do much. It really sucks, cus it is a cool riff and a cool song. The notes just kinda sound like they are one long crash of bass strings being hit at once. When I play it on other basses it doesn't change, I think it's the amp. What should I do.
