Considering that a single, high end pedal can run close to $200, the G3Xn is a good value for learning and experimenting.

The primary reasons I purchased this unit was the high number of positive reviews all over the web, the exceptional price point and the value for dollar spent

It is extremely affordable and a great value (one of a few key reasons I purchased it) especially when priced against the number of comparable analog foot pedals required to replicate the comprehensive bank of sound effects available

My only big drawbacks are: some of the pitch shifting effects have absolutely terrible tracking, and the dirt/fuzz options don't sound nearly as good as the real deal.
