Hi My name is dani, I'm buying a Harley benton sg moodel. I am a beginer and i just want to know if it is a good guitar to learn the basics, and if i have to throw to the dumpster after a couple of months?

With great respect Dani
They're terrible from what I've heard. Try an Epiphone G400 or a similar model instead.
Then there's this band called Slice The Cake...

Bunch of faggots putting random riffs together and calling it "progressive" deathcore.
Stupid name.
Probably picked "for teh lulz"

Are you getting it online or can you try it out in a shop? A lot of people seem to be buying them online from various retailers but i've never played one myself. I would imagine if it's set up well you will be fine with it to learn on.

But if there's anywhere close to you, go there to try guitars out and get some advice in person from shop owners/staff.
