There might be other/better sites that do the same thing, but recently I started using this website to check what gear musicians I like use:

It’s especially useful for effects pedals and the like, since it’s hard to identify those in videos unless you really know your stuff. It’s also nice for (well known) non-English speaking bands, since other obsessive fans who speak whatever the language in question is better than I ever will have already done the work of reading/watching through every interview and documenting any equipment that is referenced.
(It will try to convince you to register, but you can just click past all that and use it without an account.)
