I used to gig with both an LP (79 LP Custom Silverburst) and my Standard.
I used the LP mostly for slide because of the sustain...but the LP is just too dense for me. I do like that "in your face" sound...the kind that Angus gets from his axes. The LP does "sing" more, but you can make the SG sing, too if you EQ your amp right.
I really do like the gold knobs on the faded...more "vintage" look!
I think that you need to embrace the differences of each guitar. They're
all different...like your kids! Or...like food!
