Will this thing do metal? I have looked thru with the searchbar, and can't find anything. But what kind of voicing does this little thing have? I am really interested, especially if I can get higher-gain tone out of it.
Not really. The Blackhearts are more of classic rock/ 80's tones and not high gain.
with a high quality tube pedal you can get very nice high gain tones with the blackheart
Maybe with a pedal
