He's a guitarist with money to burn. He needs something heavy, ike an old Peavey combo amp with a 15 in it.
Failing that, if it's only for studio recording, and we want to pity him for having to haul his full Marshall stack all the time (or Twin Reverb with JBLS in it) perhaps a Markbass combo amp would work well for him. I have used my Minimark for many recordings (and gigs, too) with excellent results.
Exhibit A:
Mic'd with an EV RE20 to the console.
Is this a reference to the guitarist in question?
