Every time I try to use distortion stomps (mainly Kemper and green), I'm very disappointed. It sounds like the clean sound and the overdrive are played at the same time, even by setting the mix to 100%. I mean it sounds like I get the clean, and a fuzzy messy sound all together. By using cranked amps, it sounds like a complete coherent package, and turning the volume nob, makes the sound changing smoothly. Is there a trick ?
