This was a little tricky to install and have the wheels properly align over the strings, but once you get it, the gizmotron is amazing. The sounds I'm getting out of my Stratocaster are beyond my wildest dreams. A fantastic gadget for people who want to get more out of their guitars. With the right effects channeled in, I can make my guitar sound like a moog with this beast. There's also a slight learning curve to it, but play around with it for a week and you get the hang of it really quickly.
