Feature:
The most usefull feature is the ability to get to desired pre-effects immediatley every time. No need to mess with knobs by hand.

Quality:
It made from metal - no plastic it is rugged.

Value:
There is nothing like it. If you team it up with a Vypyr amp you will save hundreds or thousands of dollars in foot peddles alone.

Desirability:
I like the design you only use the midi direct in to the amp and your guitar jack still goes directly in to the amp. You contall Volume / Wah / Loops / all the Stomp boxes and Effects loop presets right from the peddle.

Sound:
This product helps one get the most from their Vypyr modeling amp.

Ease of Use:
very simple to use plugit into the midi port on back of a Vypyr and that's it.

Support:
I own several Peavey products including the Vypyr modeling amp and have been completley satisfied.

Overall:
I expect this will be in my gear for quite a while.
