Here's my review of the Tree of Life from Vick Audio. This versatile overdrive is based on the Zendrive and OCD, with a wide range of tones from transparent cleans to tube-like overdrive and distortion. I'm using a Fender Stratocaster, with DAllen Echoes pickups into a Laney Lionheart L20 mic'ed with a Shure SM57. See the full review on gilmourish.com.
