ok. well i have a hartke 2000 head, crate 115 cab and a crap johnson starter bass. anyway, here's the problem: when i play in standard, it sounds just fine. i mean, the bass sounds bad, but what i would expect. but, when i tune to drop D, the D string sounds BAD when i play fast....when i play with smooth, soft plucking (as in, a slower song) it sounds fine. but when i try to play something like black dhalia murder or slayer, or any fast heavy metal, it sounds terrible. its this weird occasional popping sound along with the regular tone. i cant stand it. i tried twisting the bass's tone and volume knobs, different combinations with the amp...still the same very annoying sound. even with the compressor on. the noise sounds the same on the little guitar amp i used to play through (only i expected that, since its a tiny guitar amp). will this sound be cured if i get a better bass, even if its just an SX?
