My new ideascale suggestion:

I would certainly be interested in a replacement processing unit that enhanced the functionality without me having to buy a new guitar - obviously
Who else would be interested in higher quality modelling and expanded feature set to fit into their existing guitar and perhaps to help Line 6... how much would you be prepared to pay?
