hi guys i need some help and recommendations on mfx.

I have a vox valvetronix amp. the amp itself has several amp models built in already, and i am looking for a mfx that goes well with it.
Basically i need good distortions, od, wah and maybe harmonisers effects, plus interface and recording with pc. Others are a plus.

Budget i set aside rm 700, or 1k top. Any recommendations? I saw products from boss or zoom but really no idea whether it pairs well with my amp... thanks.
