After an easy installation including the solderting of the jumper wire on my "older" X1, I quickly found out that it is every bit the equal of what many raved about. Exceptionally clarity and tone quality.

Tho in the short time I've used it, to me, the only drawback I see, is the lack of "country harmonizing", which has it's own harmony above lead notatation. But irregardless, it is truly and outstanding harmonizer.
