The UK went officially metric in 1973. However, the British are a nation of shopkeepers, of the variety that can't manage to adapt to the modern world, so it's all got stuck.
However, that's a diversion from GR Bass - I'm now thinking of selling my BF BB2 and Tecamp Puma 900, and replacing them with an AT Cube 800. Less weight, fewer items, and similar power. I'm playing pub gigs with an acoustic guitarist, keyboard player, and a percussionist on cajon and bongoes rather than a drummer, so I don't have to turn it up to full whack - I did try using a BF One10 but it seemed to be breaking up at just short of the volume I needed. Does this sound like a reasonably apples to apples swap?
