I rather fancy one of these myself. great little guitars, ideal for travelling.

The owner wanted an electric pickup and mini-amp fitting

It’s left handed so the mini-amp will sit this side.The corners need to be rounded off so start of with four large holes and roughly cut the sides.Next with a sharp chisel tidy up and square off the sides.Tat’s the hole for amp…Next the saddle.  Since the pickup will sit underneath it needs to be reduced by the width of the pickup otherwise the action height will be raised up.It’s only a couple of mm.Making sure the bottom is perfectly flat…and square….Lastly the jack socket.  I’ll take out the bottom strap button and mount it there…After…There we go, job done…
