Congratulations Sergio! Glad you've found a great lady. Treat her well, guitars
come and go but finding someone who cares for you is priceless.
And I like your new guitar. I played a parlor guitar onstage for a long time...
the one in my Avatar. Since I'm about 1.8 meters tall, the small guitar looked
small in my hands, but not too small. Mine was a 0-17 Martin guitar, that
I have just sold.
I bought a Dreadnought guitar as my first good guitar, because many of my
musical idols played this model. The Dreadnought was invented in like 1916
to provide gigging musicians with more volume and projection. In those days,
nothing was amplified, and the guitarist had to compete with brass and reed
instruments, as well as honky tonk piano and some drums.
Fast fwd to the '70s, when I was playing bars, and the big voice of the Dreadnought
was able to get the beat out into the audience, even if we had poor sound from the
P.A. When people are drunk, that's mostly what they hear, which is why drunks talk
so loudly. Your drummer will confirm this, of course.
These days, the big bodied guitar doesn't seem so necessary. It was named after
a famous battleship from like 1906. HMS Dreadnought...

Surely you can see the resemblance. But the small and lighter guitar can be amplified easily using
new technology. And guitar mikes are better too. And if it's to be your handy practice and writing
tool, the small and light instrument does nearly everything you need.
I own two acoustics at this time, a Dreadnought and a 000 size Martin that I really like too.
The dreadnought has its own mojo, and a commanding tone. But when you plug them both in
the smaller Martin gives up very little. It's got a sweet and even tone that has its own
personality and appeal. Because mine's smaller and lighter, I find myself reaching for it more
often.
Congratulations again!
