Here Joe is playing a Jim Kelley Reverb:
I own one of these and haven't been able to replicate it on the Helix (yet). That video is a perfect demonstration of what I'm after. So far I've gotten the closest using the "Litigator" model running into the "Mesa EXT" cab (it has an EVM12L like the real amp). I'm particularly struggling to get that note bloom... Any suggestions? Should I try a different amp model, EQ, or maybe an IR?
