Not sure what you mean by recording facility unless you are referring to the USB connection to computer which I have used and works great. I use Logic Pro X on my Mac and it recognises the Spark and shows it' in the options on screen.
I find it easy to get a good Vox AC 15/30 sound for Shadows music, even with the built in multi head echo that is based on the Roland 301. It obviously sounds even better with the TVS3, Atlantis or Stymon Volante, but very satisfactory with it's 'in house' effects.
For me the Spark amp is a very convenient small and inexpensive option to use in the home and offers jamming facilities by providing a backing track to your own chords.
