I don't think I own a single guitar that I bought brand new.
Mostly out of necessity, I've bought from Junkmail, Gumtree and, once this place existed, GFSA.
But seeing as I'm not too experienced with amps and speakers and pedals, I would seriously consider buying those brand new.
Come to think of it, I did buy 1 amp brand new. Roland Cube 15 or 30. That thing was solid.
Other amps and pedals that I bought second-hand had issues. So it's tricky.
IMO it's tough to buy reliable electronics second hand but, for guitars, I'd say it's practically required. You get stuff that has a history, mojo and, as long as you get a demo of the thing, or can try it yourself, it's probably not going to break. (Or can be fixed for much less than the price you paid.)
Won't lie though, I'd LOVE a brand-spanking new JS2450 (Muscle Car Purple *drool*)
