hey guys.. i'm trying to get my first electric,, well i can afford on of those guitars
the yamaha SG300 vs the cort evl k2
i play some rock, metal, blues songs, witch one is the best plzz
those are some pics
the cort

the yamaha

Generally speaking, it would be a no-brainer to go for the Yamaha - the japanese made SG models are consistently excellent across the entire range, and the more basic models like the 200, 300, 500 etc. can still be bought used for great prices - so you could do a whole lot worse for a whole lot more money.

However, both of the guitars pictured are in atrocious condition and most likely need some work which will probably end up costing you more money. I would recommend that you look for something in better condition, unless they are going really cheap and you can inspect them thoroughly before you buy them to make sure there's nothing wrong with them that you can't already see in the pics. If you don't know what to look out for, bring someone with you who does when you go to inspect them.
I like analogue Solid State amps that make no effort to be "tube-like", and I'm proud of it...

...A little too proud, to be honest.
