Hey, i have a 30watt marshall combo and to be honest, the tone sucks.
I'm looking to buy a blackstar amp, and i was wondering if getting the 5 watt or the 20 watt made a difference, if i put it with a 2x12 cab.
Does the wattage in the head translate to louder cab's?
Thanks UG, Tom

the amp is the one amplifying the signal...
so like..the 20W head will be louder than the 5W

the wattage of the cab makes no difference when it comes to loudness.
the cab's power rating (in watts) just tells you the maximum power that you can safely put into it. NOT how loud you'll sound


a 5W head into a 30W cab will be quieter than a 20W head into the same cab.

a 5W head into a 30W cab will be the same volume as a 5W head into a 100000000W cab

I would go with the 20 watt. i have found alot of the 5 watt amps are under powered. people i have talked to said at first they loved the amp but the only complaint was that it wasn't loud enough. Yes the wattage of the amp will make the speakers louder. unless the ohms don't match up from the amp to the cab.

Can i just clarify,
a 5 watt head going into a 2x12 cab will be quiter than a 20 watt head going into a 2x12 cab?

yep, you've got it

the wattage of the head is what makes the difference

you've just gotta make sure the cab can handle the power you're putting into it, and that the impedance matches
