Meaning two people who play off one another NOT whole bands. Mine are probably:

Flea/John Frusciante - RHCP
Keith Richards/Ronnie Wood - Rolling Stones
Brad Wilk/Timmy C - RATM (one the the best rhythm sections in all time in my opinion)
My gear:

Fender Telecaster (Mexican)
Epiphone SG (Emily The Strange edition) (first guitar)

Starfire 80 watt practice amp

Marshall 150 watt amp (deceased due to falling beer )
