Hey guys. I use a Big Muff normally for distortion in my jazz fusion/metal trio. The muff works great for me when I solo. However, when I play fast riffs with the muff on (normally during the guitar solos) the notes tend to get really really muddy. When I try turning the muff off, there's just too much empty space (it sound fine when in unison with the guitar but apart from that, it doesn't sound right). Can anyone suggest a distortion/overdrive/fuzz that does a better job at filling space when playing riffs and such or maybe a way to remedy my muff problem?
