i am pretty sure that the workingpro 12 will be my next purchase for an amp and i was just wondering if i should reconsider or not. i need an amp powerful enough to be played at gigs because my current amp is simply not loud enough
Get the Workingpro 15 unless it can (and you will) be running an extension cab with it.

1x12 combo's don't seem to move enough air.

Good amps, though.
And yet, to me, what is this quintessence of dust? Man delights not me: no, nor woman neither... nor women neither.
