I'm loving this little amp, Blackstar 5HTR, 5 watts (1 x 12) combo. It sounds great at home and even at rehearsal where I keep it dimed. It's pretty loud on its own, hard to talk over, but when the drums kick in its a little too small to cut thru the mix. I have a Tech21 Power Engine, a 60 watt (1 x 12) powered cabinet. I use it sometimes with my Trademark 60 and together they sound huge. I thought I'd give the Blackstar a shot thru it. It worked pretty well, the little 5 watt Blackstar can now be painfully loud, 60 watts loud! It's a great way to boost up the volume of this little combo. Just come out of the Blackstar's headphone jack and into the PE60's 1/4" input. The Power Engines can be found used for around $200 or so. Works for me, thought I'd pass it on.
