I recently purchased an Epiphone EF500RCCE acoustic guitar with eSonic2 electronics which has two 1/4" output jacks on it. One says MONO/both pickups(nanomag/nanoflex) this blends both pickups and the other says STEREO/nanomag which will split the two pickups. I have been using only the Mono output with a monster acoustic cable. To use the other output with a second amp do I need a different type jack (stereo) or can I just use anouther mono jack. The instruction manual has no info about how to use these two outputs.
