Report ES339 pro microphonic in split coil mode in Epiphone Electrics Posted January 19, 2015 Hi Stein and thanks! I'm rather new to semi-hollows and your comment about them being more prone to feedback makes sense given my past experience with acoustics. I'm actually splitting the coil to get a single coil spank for a few cover songs that are originally recorded with teles or strats. I'll experiment a bit. Thanks!
