Stringreen: Prior to moving up to the "R" class, I had the K-5xe/V-5xe combo. I considered moving to the "1" class, but that was before hearing what the MXR could do, it really is much better than the V-1xe. If the jump between V-1 to MXR was big, the difference from the K-1 to the KXR is enormous. Charlie, Steve, Ariel and the rest of the gang are rightly very very proud. This is a home run product that will stand the test of time. I know the "R" class is significantly more expensive, but when you consider how it will be at the cutting edge for a decade or more, and the enjoyment derived, to me it was a total no-brainer. - Pete -
