My son uses Ownhammer IRs for Riffing/DJenting and internal IRs for solos. His favorite IR is the Chinese v30 Modern Studio Mix IR: "OwnHammer_412_MAR-CB_V30-CH_SS_Studio-Modern" (I actually like using this one for solos).

I can't even find it on the site any more, but it was a Marshall Checkerbord cabinet with a bunch of speakers.

Look for these four while you're shopping around and you'll have everything you need:

Scumback M75, Chinese V30, G12M-65, and HB-55

Usually the ones with an "SS" in them for solid state power amp work for us....
