Baz, It's tough to explain, the amp has a very British feel to it, not just tone. Most of these hybrid amps sound to modern to me, I found the Terror Bass to have that vrrrrrrrrrrrrrrrrrrr in the notes played, it's a bit blurry not super tight sounding and I like that, not staccato punch/snap but lots of sustain especially on the D and G string. I like it you may not, I am not saying that it is just like a Hiwatt but that it is a good stand in for my application.
