I re-did the ground solder joint once again and it is a lot better. I would have to use an amp to rule out the other half of the setup here.
Anyhow, I have been playing around for a while and am ready to give a final followup on the upgrade.
Surprisingly, I like the cleans better than my old pickups. I didn't think this would be the case, but I guess the older ones had a twangy quality that struck me the wrong way. The cleans are very clear and crisp, and I absolutely love it. I am really surprised because I wanted pickups that were more suited to heavy stuff like opeth or btbam that I have really been into lately. I like to play mainly in the bridge under heavy stuff but both pickups on clean really sounds phenomenal now. These pickups make me regret doubting the quality of my guitar; clean sounds are just so beautiful.
The heavies are definitely better. Again, crisp and tight, and palm mutes actually have power to them now! No muddiness on the lower side and long open opeth chords sounds clear and defined even under ridiculous gain.
Overall, I think these pickups are perfect for me. I don't excel at any one style and really enjoy having an instrument that I love sound good at most applications. I have been converted to BKP for sure.
I cannot express how grateful I am for all your help, I couldn't have done it without you guys and I really appreciate it.
One question though, can anyone out there enlighten me on pickup height for these kinds of pickups? I have mine almost flush with the black plastic pickup cover and they sound great, are they too hot to bring up closer to the strings?
