I've been looking for a powerful sound system that's impression is as good as its sound. I looked at the classic Ampeg 8x10 with a matching head. i'm still open to other suggestions (i liked a few Gallien-Kruegers but I don't know what exactly to choose) and I'm also curious, will the Ampeg SVT450H have enough power to use the SVT-810E? also what kind of power supply would i need to use it? cause I practice normally in my bandmate's garage.
