Or you can buy a used one like my G400 for under $200. Spend a few bucks on upgrades and have it play and sound as good as a genuine SG for several times the bucks. And that assessment doesn’t come from me since I’m basically clueless. That came from a guy who’s played electric guitars for decades and has owned and played a bazillion different guitars.
Fully recognizing it will never be a Gibson SG. Will never have the resale of an SG. Will probably never get back the money spent on it…. But since I have no plans of selling…. Who cares??
Before I got my hands on a Gibson SG Standard, the first guitar I ever bought with my own money was a 96 Epiphone G400. I think it was about $350 new, if I remember correctly. The pickups were absolutely terrible ( back of them said Sam Sung, not Samsung lol). I had them swapped out for a Gibson 498T/490R set and copper shielded the cavities.
Due to trying and failing to do this myself ( I WAS 13 after all lol), the bridge wires ended up being almost too short to do anything with, so the guy who did it for me inverted the layout: bottom Volume and Tone operates the neck, top volume and tone operates the bridge lol
Still own the guitar actually and have debated making it another Frankenstein project just for the fun of it. I have never sold a guitar I have ever owned ( did sell a few amps regrettably), so being that it probably won't go anywhere? Might as well mod and rebuild it. Considered making a discount version of Tony Iommi's Monkey SG or maybe even repainting it black and dressing out the electronics.
I did this once before on a cheap hollow body called a Kansas ( allegedly made by Cort sometime in the late 90s) that my dad bought from a pawnshop for about $200. Body was mahogany with a maple sunburst top, mahogany neck, rosewood fretboard. Seemed like a great structure overall but with just awful components. So I asked dad if I could upgrade it and he said sure. Ended up spending nearly 3x it's original cost lol. All Gibson hardware replacements from the stopbar, bridge, pots, pickguard, switch and knobs. Put some Grover Mini Tuners and a Gibson 57 Classic Plus in the neck with a Gibson Burstbucker 2 in the bridge. Crazy cost over run but it absolutely roars and plays insanely easy. So, fun experiment!
