I just bought this setup new less than a week ago. And I just canNOT get a clean tone out of this thing. I know the GK "growl" is a popular term, but what I hear is distortion. I've been messing with the rig for a few hours each day, and trying all kinds of combinations with the knobs. For example, if I turn all knobs all the way off/down on the amp, and roll only the Volume and Woofer knobs all the way up, when I play the low E, it sounds like a distorted fart. (After a few seconds the distortion falls off.) I know this isn't a good setting to get a good tone, but I don't think that distorted sound should be there. To me, that setting should have mostly a clean sound, especially with no boost. When I have the Volume, Woofer, and Boost knobs only halfway up, with the EQ set in different ways, the rig is loud, sure, but I can't get a clean tone. And the louder the amp gets turned up, the more the "distortion" is prevalent. My bass isn't primo, but it isn't bad; I have a Schecter Stiletto 4. (I just changed the battery in the bass today.) This GK stuff is my first loud rig, as I had been playing with GK MB115. I have friend who has a Genz Benz Streamliner 900, so I'm interested to hear what the cabinet sounds like with a different amp. Otherwise, I'm having a hard time finding a sound I like with this GK rig. I'm hoping someone can tell me I'm doing something wrong. But I don't think getting a clean bass sound/tone is too much to ask? Maybe just not with GK?
