Z.Vex makes some of the most unique and interesting effects ever made. They are hand made and painted in Minneapolis, MN by Zachary Vex and his analog elves. They have been reviewed in Vintage Guitar magazine 1/97, Guitar World 5 and 12/97, Keyboard 12/97, Guitar Player 5,6 and 11/97, Guitar Shop 5/97, and Harmony central reviews. Now you should GET ONE! before economics could force Zachary to have them mass produced and they would lose their soul. All have super low current flow (battery lasts forever, at least a few years), hand built and painted (cool graphics!), and major MOJO. The circuit boards are machine milled rather than chemically etched, eliminating any pollutants in that process. The Ozone layer thanks Z.Vex!
