I know Richie uses a lot of Boss pedals. And you can clearely see that there is a couple of Boss pedals there. I'm pretty sure he uses:
Boss SD-1 super Overdrive (Not sure he have it on Crush, but he had it on 80s and 90s)
Boss BF-2 Flanger
Boss TR-2 Tremolo
Boss CH-1 Chorus
Boss RV-3 Reverb/delay
It's possible he uses some kind of effect pedal, probably a Dunlop CryBaby. I'm pretty sure he use a Dunlop Talkbox. As amplifier he used a
Marshall JCM 2000 TSL601 on the Crush Tour and One Wild Night Tour. With this set up I'm pretty sure you will get a sound pretty close to Richies !
Hope it helped !
