i know there's plenty of threads out there talking about grounding and shielding, both of which i've already done, but has anyone changed/swapped their stock pickups for different, quieter ones? the odd thing is that i don't notice the buzzing-hum with my amp, ONLY when i'm running it direct with a Tech 21 Leeds. i step on my OD's which are both pretty darn quiet, and BAM! unusable buzzing loudness! again, i don't get/hear the issue with my amp, just running ODs> LEEDS> Timeline> Space. i've been considering the Seymour Duncan Antiquity II pickups. thoughts?
