I'd been fooling around with blues and like it very much but found myself pushing the amp (a Supro 1970RK) to beyond its wheelhouse. I was inching more toward a grind and grit that even a decent pedal couldn't produce in that amp. Heavy distortion, fuzz, etc., just made a great amp sound like shit.
And Black Sabbath, and the desert sounds just seemed to call to me.
Lusting after one of these for a while, I found a Blackstar Series One in 50W on the local market and snapped it up. I spent the last couple days getting a cab, leads, etc., to get going. So far, so good. With the built-in attenuator, I can dial it all the way down to 5W if I want to but I tend to stay around 20W.
A TS9 pushing the crunch channel is where I find myself. I also picked up a Black Arts Toneworks Crown of Horns which is essentially Stoner Metal in a box. On the warm clean channel, it just produces instant lovable sludge.
