My immediate goal is to be able to record songs to share with friends. I have no aspirations of becoming a recording artist or YouTube star. However, I do appreciate quality and was considering the purchase of a Shure SM57 when I came across the much less expensive and much praised Pyle PDMIC78. The microphone will be used to record my guitar amp in conjunction with backing tracks in GarageBand. I have a Presonus Inspire 1384 to use as an interface. All of the reviews I've watched and read indicate that the sound reproduced by the two mics are similar, but not exactly alike. The Shure has a built in transformer, while the Pyle doesn't. A Shure is around $75 used and $100 new and a new Pyle $15, plus the cost of a stand clip. I usually lean toward name brands or industry standards, but between the acclaim that the Pyle receives and the $50-$75 price difference, it seems that the Pyle is the best choice. I'd appreciate your input especially if you have experience with the Pyle PDMIC78.
