Seriously fellas ...i don't want to repackage a dead mule or sell hype...
That's true.
This pedal isn't for everyone but it is everything that you, the person who wants amp-like in-your-face grind, want.
You wouldn't get sweet bluesy tones here with tubescreamer like sustain. Nope.
No boxy-ness happening.
Heck, the thing doesn't have the compression you'd expect from a high gain pedal - its that natural. Increase your volume if you want the compression.
The low gain side of things remind me of... wide open grind. There's plenty of jangle. Very very excellent for strummy/riffy stuff. Extremely dynamic. Dig in, you get more distortion going on. Yes, its distortion, not overdrive. Personally, the vibe I get from this setting makes me want to just bang away at the guitar.
The high gain side of things give you the more modern-ish high gain metal tones. There's lots of clarity available, a lot of grind and a lot of low end. As evident in the clips - you can chug. No bees in a box. There is more compression but you have an extreme wide range to play with because now, lighter picking actually does clearly change your sounds.
All in all, very big. There's only 1 other pedal that sounds this big and thats the Toneczar Openhaus. Maybe the older Krank Distortus Maximus. All my fuzz pedals sound smaller when the Seventheaven is run on 18v.
9v is what most people are running it at I presume... that's a more manageable "mode" than 18v because on 18v, the thing sounds... ridiculous. Every knob, every setting, all sounds - now go to 11.
