I just recieved my dual rec back from voodoo amps with the deluxe mod and Ruby tubes and I can tell you it sounds awesome. Its sounds as good as claimed on their web site and as good as everyone on this forum said it would. The amp was packed so well it took me 10 minutes to get the bubble wrap off of it. I wish I could post clips, but I am not set up to do it. It could be the deluxe mod, but the clips on the site don't give enough justice to the sounds I am getting from this amp now.
