I have an sg pro, looks similar to this exact one, struggling with middle position. I had a great sounding middle position with neck on full, bridge at half. Sounded like a beast inside my pickups trying to get out. Then I took my guitar into a luthier, paid half the price of the guitar, got it back with the pickups so high that they warbled. I spent a weekend or two adjusting the pickups. Bridge - 1.6mm bass and treble side. Neck - 2.2mm bass and treble side. This way I thought I had 3 distinct tones, but I couldn't find my beastly tone ever again... failing that tone I once had, I would settle for the tone in the video. That's the tone I associate with SG sound. Can't get that either... Any help would be appreciated. I've spent countless hours messing with pickup heights, currently the sound is just decent, without any major volume difference.
