Any profile suggestions to get close to this tone?
It doesn't need to be a JCM. Maybe some profiles of other amps get even closer anyway, depending on micing, cabs and how they are dialed in.
It's more about these things, I find, than simply the amp itself. Also I'm using active Fishman Fluence pickups to get close to his tone (close to EMG 81). So a set up dialed in for these type of pickups and profiled may work best.
