Awesome and simple
Great heavy tone without tweaking. Can't get much simpler than this while retaining great sound. Very happy with all the Ampknob series.

Love at First sight…
I bought this AmpKnob BH4 and also the two issued from a barely known guitarist named Eddy Van Halen 😁
This BH4 truly almost scared me because playing with it’s just like juggle with a stick of dynamite Ready to explose in one hand and a bottle of nytroglycerine on the other, this AmpKnob is powerfull not brutal but sharp, the Sound is define and still, it’s easy to use.
From my point of view, it’s just a very good tool.
