Seymour Duncan SA-6 Mag Mic

I have tried many acoustic guitar pickups over the years and was disappointed every time. Finally Seymour Duncan comes through with the Mag Mic pickup ! I have the mic at around 50 percent for accurate natural acoustic guitar sound. I have purchase 3 different types of pickups from LRB , they've all been a waste of $. This mag mic delivers the goods. Uses a 9 volt battery, installs into the end block but has a spacer to go through the side of your guitar as well. I put this on 2 different guitars an Epiphone jumbo and a concert size, sounds better on the concert size Taylor 314CE. I do not know anything about the feedback for live use, but it tracks great in the recording studio. I got super mega fast shipping from Music123 and will be back for more great stuff from them.
