Hey Bongo - I realize it was a bit of a lazy question!
It may have to be a little schizophrenic in nature. My cover gig at the moment is acoustic duo, which I will primarily only use this cab for alone with an MXR M80 to boost signal and enhance tone a little.
My original music gig however is metal - sort of a cross between Metallica chunk and Euro melody, and in this instance I will use the above setup with an 8 ohm 4x10 cab (400 watt max output).
Not sure exactly what my budget will be in $ - willing to consider something between $500 - $1000 AUD I guess. Would prefer to buy locally as well and will probably stick to brands that are available in most areas around the world.
I like modern punchy tones.
As for the sensitivity off my current cab Im sorry I dont know what that means
