Update: The 10s, in combination with the Blackouts AHB-1 bridge and the Blackouts Strat AS-1 neck, did it. The bridge pick attack that had been harsh before has just turned into a good part of the character of the guitar. With the lower mids and bass from the pickup now supporting the sharp upper mids of the guitar itself, it now sounds balanced, with a cool bite that gives it its own vibe, in a good way. So the Blackouts HS set were the first piece of the puzzle, but by themselves they did not entirely balance the harshness with 9 guage balanced tension straings; I needed the balanced tension 10s to finish the balance. And of course, with the higher tension I was able to lower the action, which is a bonus. Going back to 10s was the smallest deal ever. It took no time to set up the guitar, and, because I played 10s for so so long, it feel actually more right to go back.
The difference between the tone of 9s and 10s of the same type string in the same brand might be subtle for some, but it is fucking huge for me. I mean, just night and day. I could almost feel my guitar breathing a sigh of relief, like he could finally deal with his own tone better. Everything all of sudden had the right attack, the right roundness, the right balance.
I've had this guitar for a few years now, but this is the first time I feel completely at home with any bridge pickup in there. The neck Strat pickup is nice and thick, and this really helps mitigate the fact that this is a 24 fret guitar; I'm getting neck tones that have the warmth I've been looking for, what I think of as "22 fret tone," at every output level. I just got in a capacitor assortment for me finally to install a tone cap for the neck, and I have no doubt at all, with it's massive output, that if I just roll back the tone knob, I'll be able to cop neck humbucker tones if the mood arises. And with the volume rolled way back, the neck puts out beautiful Fender clean tones. And the bridge has all the versatility I was looking for, every kind of Plexi tone rolled back, to any kind of metal tone I'm inclined to dial in at the moment. The beef and chunk is there now, with the cool attack, so it's ideal for tilting the tone in whatever direction I want.
I always play for my ears. If my tone is not right, I'm not right, and my playing isn't right. It's like my playing is entirely in service of my tone. So I feel like, for the first time since I got this guitar three years ago, I can finally embrace the instrument as a whole.
By the way, I found an M4 0.7 pitch dome cap hex screw at the local hardware store that fit my Floyd locking nut in the meantime, while I have new nut locking screws on order. I actually like the look better than the standard Floyd screws haha.
So I think, after this tone cap goes in on the neck, the guitar can just rest and start being played properly. This is a huge thing for me, and I can't wait to get into it now and reestablish my relationship with this guitar.
