Murray is obviously assumimg you are going to have a socket/Strap button combination , rather than a jack socket fitted elsewhere.I would go along with that myself - I have an Ashworth under the bridge transducer on my 1970 D35, with a strapbutton socket fitted by a
qualified Luthier. I have the same arrangement on my Docherty mando,
fitted by Terry Docherty on build.
One thing I am not sure about - The pickup - It sounds like an electric pick up ( I do NOT know the model) but why put an Electric Pickup on a GOOD acoustic, rather than a transducer,which will give a better acoustic sound.
Incidentally I have also used Microvox to very good effect , but you
are liable to some feedback problems if you want to be TOO loud.
