In the early days, Pete Willis especially used a wah wah pedal on almost all of his solos, Steve rarely used one, exceptions are "It Don’t Matter" and "When the Walls Came Tumblin' Down", - so usually when you hear a wah wah in the pre Phil days, that’s Pete – everything else is Steve.
When it comes to Steve and Phil, it’s much more clearer I think. Phil plays speedy triplets with more tremolo screams. Steve bends a lot more than Phil, with less tremolo. Those are guitar terms, but the more you listen to the different solos especially live, you will know what I mean.
I want to stress that, live is the way to distinguish the styles, not necessarily studio work. Many times they use different guitars, play each others parts and do overdubs, which would happen in a live setting. For instance, Pete Willis didn’t use the wah wah so pronounced on record, when he played live, that’s all you heard. Steve rarely played fast triplets on record, but live Steve was a much more flashier player. You need to listen to Def Leppard live to appreciate Steve’s style.
