The Juicy77 is currently free and in beta from new plug developer BTE Audio. Since it was free I decided to give it a try and see if it was worth the download. Here's what BTE has to say about it:

With separate preamplifier and power amplifier sections and a loudspeaker cabinet simulator section that includes seven classical cabinet types, Juicy77 modestly delivers instant gratification to musicians who are looking for the ultimate high gain experience.

So anyways, download the zip file below and give a listen to two very different patches. I must say, there is a good amount of depth to this sound, particularly the clean sample. It almost fools the ear into thinking the sound moved some air at some point.
