I personally find this to be a God-Send for tweaks and alternate tunings.
Although the Variax 700 is long in the tooth and doesn't offer a million slots for your own set-ups, the Workbench is essential and I use it almost daily all these years later.
It is plastic, you do have to use Line6 Monkey (which can be quirky on OS X) but overall I am a very happy user.
Pros - it offers quite a lot of tweaking for my main guitar, the 700. The ability to set my own tuning per (user) slot and on one model I like to have one string louder (in my case the G string) - Workbench allows me to easily do this.
Cons - not everyone will instantly fall in love with the software you need to use BEFORE you can get into using WorkBench - Line6 Monkey. I dont hate it but it wouldn't be my 1st choice either. Its functional and gets me into the WorkBench software without too much fuss.
The unit is lightweight and plastic so I would recommend doing your set-ups at home or in the studio before hitting the road or stage. But then again this hardware is not meant to be used out live - just save your 5 slots (or tweak the inbuilt preset models) and your good to go.
Finally - if anything its a little costly for how much you will use it. Once you find your ideal set-up you can tweak away but more often than not its just set and forget on your Variax. No real need to go back to WorkBench once you have a set-up your happy with. Of course you can always try new things!
Were I to misplace mine I wouldn't hesitate to get another. Heartily recommended if you have a Variax 700 and want to try something different from the stock set-ups.
