    Fantastic sound! With a few issues... by Michael

    Let me preface this review by saying I just got this pedal in yesterday but I did play around with it for about 6 hours. The sound is very subtle but quite rich. The Pre-amp side adds a touch of clarity on the top end and some body in the low-mids. The boost is quite nice as well. The boost side seemed to be very transparent, which is a word that I think is thrown around too much. But I really feel as though I'm just hearing my amp being pushed more and that any extra overdrive I'm hearing is coming from the amp being saturated with signal rather than the pedal creating noise, and there seem to be no added eq tweaks, which is exactly what I was looking for. There were some negatives I experienced but they didn't necessarily impact the tonal quality. The input gain pot was extremely scratchy straight out of the box. Once set however, there were no noticeable extra noises. Also the switches give a noticeable "pop" when pressed. I would like to use this pedal in a live setting but if the "poping" remains a problem I don't really see myself using it there. Which is a shame because, again, the pedal sounds really nice.
