I bought a very early version of the Composite Acoustic Cargo.
It's a small body with a pickup built in, great for travel.
For many years lived on a boat from April thru Oct so, I was always on the hunt for a guitar that would hold up in that environment.
Currently it's my only acoustic and I've never really used it plugged in.
If you've heard any of my acoustic songs, that what I used.
I just started experimenting by going into a D/I on my recording pre-amp. ..wow!.....I like it.
I was expecting a very thin sound, wrong, I'll probably use it on my next song so, you'll hear it then.

After purchasing the acoustic, Composite Acoustic began experimented with a full electric carbon fiber guitar called the Blade.
I bought #61 and soon thereafter they went out of business and eventually sold the brand to Peavey.
I think Peavey still makes the acoustics but, not the electric Blade.

Also,
I've thinking about picking up a small bass to supplement my recordings.
One that is on the sort list is a carbon fiber that breaks down for travel.
It's made my Journey guitars.

Bottom line I'm very happy with both of my carbon fiber guitars and I might buy a carbon fiber bass to boot.
