I feel like funk is really more a function of the player vs the instrument (well, that's true for most about anything), but I'd probably look for something with single coils. Can't really go wrong with a Strat style guitar. Locking tuners are good, but depending on how aggressive you are with your bends, may be unsatisfactory. In which case probably want to take a look at locking trems. I've heard they're a pain in the ass though, I used to get by with just locking tuners and stretching my strings. I never used lots of bends, though.
If you're feeling adventurous, take a look at
Shijie guitars. Chinese brand, but heard lots of
good things, and are supposed to be fantastic value for the money.
Re: amps, can't help much there, if you like Marshalls, go for it! I've kinda been eyeing
Blackstar amps, might be worth testing one out (the founders used to work at Marshall).
Too bad
@KCWM isn't around anymore, he was a bit of a gearhead.
