one of my friend's friend wants to sell me one for 350$.. but idk anything about guits, iso opinions, and if not a good deal, what would be a good guit for a decent price?

Is it anything like this :



Bottom one, DK2 Dinky

Should have Seymour Duncan humbuckers, and it retails for $750

If this matches, you've got a good deal

second one, different color, with a little arm(idk what its used for) maybe distortion?

Are the pickups the same? Does it have two knobs and a toggle switch like the one pictured? Also what color is it?

If it is a DK2, and in near perfect shape, then that's a fair price. If there is any damage, or it's a lower model, don't pay more than $250 for it or you won't be able to get rid of it for a decent amount.

350 is a rip off

just get pictures of it and then we can tell you
