I like this plug a lot. The ability to load IRs is a very nice touch. This amp sim is very very good at making outrageously distorted f'**ked up guitar sounds like Hendrix at Monterey, the Stooges or "I heard her call my name" by Velvet Underground. It's also capable of some very nice retro "dirty-clean" sounds.
It's perhaps not ideal for faceless hi-fi wall of distorted guitars like all those American nu-rock bands, but that's not my bag anyway.
BTW, there are some really nice speaker cabinet impulses over at http://www.noisevault.com
This last week, I upgraded one of my computers from Windows XP to Win7. I did this by completely reformatting my partition, and installing everything from scratch.
When it came time to install and authorize all my Voxengo plugs, I was delighted to find something no regular user encounters on a day to day basis - that there is a means to authorize all my licensed Voxengos in a single action. That is some very clever and very considerate programming, and greatly appreciated by someone faced with the tedious task of installing and authorizing dozens of programs and plugins.
Voxengo plugins are an integral part of my working process now, and just about everything I turn out has been touched in one way or another by your work. Thanks very much for the great sound, and the little touches that are the product of great programming.
