I'm sorry i forgot to introduce my self.
I'm the happy owner of blackstar dual ht and HT5RH ministack amp. I'm from Indonesia.
just bought the ht5rh ministack, yes, the new one with two 1x12 cabs. I use my tcelectronic gsystem to control amp channel and for the post effects. Connect them in simple way, 2 cables method, great result, no tone loss to my ear.
