Getting a Takamine preamp out of the guitar body is something that’s confusion to many. There are no obvious screws or clips. There’s a hole that might do something but, just one. What gives?
This guitar's see better days. You can see a couple of nasty cracks along the shoulder. They begun at the preamp cutout and because of the tension on that area of bent wood, they easily spread as the centre 'relaxed' while the edges stayed in place, bound to the top and back.
Someone has had a go at repairing this damage already. The previous repairer tried using fibreglass and some mesh tape to secure things. A brace was added near the preamp cutout to reinforce it but that and the fibreglass weren't enough. The arrow shows where that brace has broken. The crack's back.
Ok, so you’ve got to admit that's a little unusual.
What we’ve got is a tailpiece installed on this Takamine. It’s anchoring the strings which pass through the (pinless) bridge and up over the saddles.
Whatever else, it’s an inventive solution to some sort of problem.
Thing is, it’s not the best solution. The tailpiece is resting against the top of the guitar with isn’t the best for getting a good tone. Also, the guitar’s designed to have strings couple to the bridge for good transfer to the top.
