Was in Montreal for the weekend. A buddy there has just bought a Blackstar 1 watt head with reverb and a matching 1x12 cab, though it's rated for 50 watts. I WAS AMAZED!
This thing is astoundingly loud, girthy, ballsy, with a nice clean and a devastating grind side. Everything I like about Rob Rose's Soloist 60, well, almost; is in this tiny thing. I always thought 5 watt amps were pointless for anything but bedroom shredding and tiny studios, but this amp can fill all those niches. Ya gotta check one out!
