I have the B450 MKII from them, I like the amp, really powerful and throaty midrange for me, but so much of the tone is in the fingers. Nice bottom to it as well. I’d just play around the with tone knobs until you find the right setting, or she do it, whatever sounds good to your ears. But they’re a great company.
sidenote: the onboard distortion for them is usually pretty bad, if you want a good bass distortion I’d recommend the Big Muff Pi Bass distortion
