It's a class D amp head with analogic preamp. I owned one since this summer (2018). It's not intender for quiet home practice because it has no headphone plug and even at low volume it's too loud.
It's powerful and it has low ends. The EQ has been designed in order to have the smallest possible impact on the volume: when you raise a frequency, it lowers another one (generaly in the middles) so you don't have to correct the overall volume if you set it first.
3 switchs boost frequencies and 2 of them can also cut (low and high). I use them first and then I turned the buttons to finish shaping my sound.
Some of the usual nice features are present: mute button, pre/post EQ for DI, very quiet fan, jack plug inserted in the speakon one.
This amp sounds good and loud but it's not completely all-round, it's not for those who wants vintage tone. Quite neutral, I think it can do with any cab.
