Haven’t tried a Vlogg. Seems darker and maybe softer than the Silenoz, but would have to try one to really know. The ultra was not a keeper for me, but very different flavor than the Silenoz
The Silenoz has that Scandinavian black metal-ish sound (especially in the highs) that probably won’t appeal to everyone. I like that is has this killer, unique uppermid grind that none of my other amps get and it gives the amp a certain cut and clarity. It basically to me sounds like a jcm800 that was tweaked to be more modern and black metal-ish. I think it’s cool, but more specific in when it would be used. The uppermid grind reminds me of some Engl’s I had, but imo better
