    This acoustic pickup system is great for the price. The eq is very useable and it sounds nice. Instalation is pretty straight forward but there are a few things you have to watch out for. The first thing I did was to cut the heat shrink off of the transducer. This was for better vibration transfer between the saddle and transducer. The rubber heat shrink acts as a damper resulting in a thinner sound. When you file your bridge saddle down make sure it is dead flat or you will have a string or two thats not as loud as the rest. It is a piezo system so even pressure has to be applied across the transducer. My A string was a bit thin sounding, this was easily fixed with a piece of aluminum tape stuck under the saddle under the A string. It will take some time and patience to get all strings even. I also dont care for the output jack that came with the system. I replaced it with an end pin jack designed for an acoustic. Using the jack that came with the system would have been very unprofesional looking. All in all its a great sounding system at an unbeatable price.
