All user reviews for the Fender Slide

Purchased today, I was looking for an interface to plug my guitar on my iPad. Comes with 2 connectors (USB and lightning), we can plug it into ipad or pc. A volume control, a headphone output, and a mix dry / wet, for no switch against hi Z, shame ...
The sound is good, a slight lag is noticeable but just configure their apps (jam xt pro for me) in low latency and it rolls. Against by not including the interest of the dry / wet mix that allows her guitar untreated / treated her, a sort of direct monitoring?
Anyway, I will try to trade him, the absence of HI Z switch bothers me to connect my active guitars.
