I started with a Cub (2x5) as a practise tool, then added the PB300, powered cab and gigged that a lot. I then replaced the Cub with a Bass Buddy for an even smaller rig, which also did the job fine, but I finally ended up with a Flightcase (4x5) on top of the PB300 as I liked the idea of having a more powerful head for when I don’t need the ‘big rig’. Every version of my PJ setups have never failed to deliver, whether using a 5 stringer or an octave box, there’s plenty of clear, low end. For complete transparency, in case you haven’t guessed already, I’m a Phil Jones fanboy, but with good reason.
