I'd have said "Powerball was so weak... in this clip". Lekteri gets great tones with his Screamer. And i have heard similarly good sounding clips from the PB.
I quite liked the Powerball tone, but it seems to share a similar trait with the Fireball, and thats this annoying fizzyness that lies over the core tone. Overall I liked the Krank best and the 5150 least.
Yeah Scar simmetry albums are all powerball: FAAAAAT tone, but I think is really one of the few examples of how it can sound good ....sometimes.
beside those scar simmetry (yeah maybe even the last the haunted... but I don't think is great anyway) albums the rest is not that great.
