We make no secret here at BP about how much we’re impressed by Tech21 gear, not least because we’ve tried – and failed – many times over the years to trick their various SansAmps into thinking we’re not Steve Harris, Dug Pinnick or Geddy Lee. No, this is not a paid-for ad page – the things just work, which is why we’re keen to play through their new Bass Fly Rig, a transportable version of the venerable SansAmp.
