I was very disappointed with the sound of this unit. The "vibe" effect (it's actually a Univibe-type effect, not true vibrato) sounded very "fake" to me (not at all like the Cool Cat Vibe from the same company). There was a noticeable volume drop when the effect was engaged, and I also heard some noise in my signal chain when the effect was not engaged. Combined with the (known) cheap construction, that made this pedal a big disappointment.
