I never used to like SGs either.
Then I played one.
Now they're one of my absolute favourite guitar designs of all time.
I love the sound. Raunchy, angry and pissed off. They're like the little skinny bastard in the fight who takes out a guy twice his size just because he fights to the bitter end, he's got that attitude, that desperation and desire to win. That's what an SG sounds like to me. Yeah, the Les Paul has more bulk and weight behind it but an SG just sounds like it'll tear it to shreds.
The cool thing is that that's not all it does. Some of the best clean tones I've ever had came from a '59n in an SG. Some of the fattest, smoothest bridge lead tones I've ever had came from a Custom 8 in an SG.
The fret access is unparalleled. Get one with a neck shape you like and there's literally NOTHING holding you back.
Neck heaviness isn't really a big issue for me. Spent 30 minutes playing it and you'll learn to deal with it. It's really not as big an inconvenience as so many people like to make out. I've played some seriously neck-heavy Telecasters too. So, neck-heaviness isn't restricted to SGs and, most importantly, NOT all SGs are neck-heavy to begin with.
I'll agree that the strap button on the back sucks. I moved mine to the upper horn and it handles much better and much more comfortably. Really helped with the neck-heaviness too.
At the end of the day, if you don't get them then you don't get them. That's cool. Doesn't really mean anything other than that not everyone on the planet is the same.
I ****ing love them.
