Lol, don't feel bad. I've been in that situation too.
My wife bought me my first Electric Guitar...
It was a Wal-Mart brand "First Act" guitar. It sounded better unplugged than when hooked up to an amp.
So eventually it got put in the back of the closet a year later when I got better at playing and got my silverburst les paul.
I just told her the truth...
It would cost us more money and time to get the "First Act" guitar setup to sound good and work right than it would cost to get the guitar I need.
But I can't ever throw it away.
It has great sentimental value...

The funny thing is that I had a feeling those Esteban guitars would be crap. The only thing fancy about those is the paint job. I'm pretty sure the electronics in the thing are junk too...
I wouldn't mind seeing any of the paperwork that comes with it...lol.
Well, on my acoustic I have Ernie Ball Slinkys. My yamaha is naturally very bassy and the slinkies even the tone and brighten it up so that it still booms but has good high end too.
