Default Cordoba Fusion 'soundport'

I've got a (relatively) inexpensive Cordoba Fusion 12. My luthier (expertly) installed an LB6, and I asked him to disconnect the onboard preamp, as I am using an outboard.

So the onboard preamp serves no function now. When I open the door to the preamp, as if I were to change the battery, it creates a partial soundport of sorts. The volume coming back to me as the player increases maybe 15%. It is noticeable.

I play this guitar both plugged in, and acsoustically. Aesthetics aside, is there any downside to taking this preamp out, and leaving an opening in the guitar, of about 2x3.5"? Thanks

The only downside to taking the preamp out is the visual impact that the hole in the side makes. As a rule, guitars with factory-installed electronics and onboard preamps are reinforced along the edges of the hole where the preamp gets installed, so if you remove the preamp the side will still be structurally stable.

Yanking out these so-called “barndoor” preamps is an easy way to give yourself a guitar with a soundport without having to cut into the side. Lots of people have done that, and it works just fine.

Hope this helps.

strikes me that it would take out a really ugly thing and replace it with a really ugly hole. You might get the sense that I really dislike the control package stuck in the side of an otherwise pretty guitar deal. You might be able to make an attractive cover that retained the acoustic advantage of the hole. Experiment with it. Adding a sound port can raise the free air resonance of the box, and change not only the percieved volume but also the fundamental tone. If you have a deadish note, that might change.
