so im looking at getting the Blackstar HT-5 5W Combo Amplifier but im not sure if i should get the combo or the head and cab. i think im favouring the combo because its cheaper but what kind of distortion can you get out of this, i want bfmv atreyu metallica trivium levels of distortion and is it loud enough to be heard over drums (very important, but bear in mind when i crank the spider 3 15 watt to about 5 or 6 i can hear it)
