This in itself would have represented a tall order, but Randall Smith went several steps further by incorporating Multi-Watt switching per channel, a Variac mode, one of the greatest clean channels ever devised, Mesa’s now industry-standard spring reverb, and much more.

When released in 2009, the Mark V had several very large pairs of shoes to fill.
