[Dawsons](http://www.dawsons.co.uk/blog/mercury-prize-royal-blood-gear), a music store from the UK, posts an article on the Equipment of Royal Blood. They write "Speaking of amps, Mike feeds his bass into a number of guitar amps, namely a Fender Supersonic and a [Bassman](http://equipboard.com/items/fender-bassman-410-neo). The Supersonic is an interesting amp, with enough gain available on tap to serve up the thick, goopy levels of grit and dirtiness, yet can also deliver Fender’s traditional sparkling cleans if required."more
A member of CHON states "we used the same amps that we use live, which is a fender supersonic and a vox ac30" in response to a question asked during their reddit AMA. You can see Mario playing through this amp in CHON's live sets such as https://www.youtube.com/watch?v=kabrEkr8quo where it is visible several times throughout the video; an example is around 18:19.more
This is a great gigging amp. The clean channel is very loud and the difference in volume between viblrolux and the bassman channel is a lot. It can be controlled with a volume or eq pedal though.
Loads of differnet gain settings available and the reverb is brilliant as you'd expect.
Cons: volume difference between channels is annoying, reverb would be better if it could be controlled with the foot switch. Hum on clean channel is a bit annoying but I use a Noise Gate to control it.
