Does anyone out there know about or use this product by Aurelex? GRAMMA="Gig & Recording Amplifier & Monitor Modulation Attenuator". The promo's claims that when you set your amp/cabinet on top of it, it cuts down room noise and makes your sound tighter and punchier, and increases low end to boot. Thinking of going after this, everybody's two cents are welcome! Oh yeh, and if anyone knows of any vendors in the GTA, Halton, or Hamilton readers, I'd appreciate feedback on that as well!
