after having my amp retubed with a clean bill of health and feeling fairly certain my speakers should be in good condition, i think my stingray 4's tone is suffering. i've got GHS boomers on and play in a weird tuning: CACA, puns & all. tone i want: throbbing semi dubby yet VERY punchy in low mids, minimal to no fret noise, singing reasonably zingy mids. i play very aggressively with a pick, problematic tone is: very clacky/clicky, with little to no high mids, but with good thick low end. the worst is the midrange, i seem to only get either cardboard sounding dull mids or a harsh, nasally tone. the clack is so bad i can hear it even in a dense droptuned guitar mix. i have to turn the high mids up all the way on the amp to get a decent springy tone. i've tried EQing the bass and amp to death and can't find a middle ground. would adjusting the pickup height help at all? i've never done it myself. i assume tightening the screws to lower it would be a good shot? rig is stingray 4 > svt-cl > ampeg 810e. style of music is doom/ experimental. thanks.
