It's impossible to answer this question in absolute terms. It's all about the stage volume of your group and the loudest member. Having said that, I've used mine frequently to gig and like it very much. It's been converted to a head (all original electronics) to drive an 8 ohm 2X12 cab with WGS Reaper HP and Retro 30....always mic'd so as to keep stage volume reasonable and allowing the PA to do the heavy lifting. Great sound with and w/o pedals IMO. Not as 'pristine' clean as Fender 6l6 and 6v6, but I like 'near edge' of breakup.
