I second to jjrpilot.
I always enjoy a process of "growing" a new guitar.
As Phil said, it is a kind of gamble. You never know how a guitar grows.
It's a bit like parenting. It is unpredictable what a child grows into. But to me, watching how he/she grows is the most enjoyable thing.
And I believe that one can influence the direction how a child/guitar grows.
So my suggestion is to play your 814 a lot. Play your favorite tunes with your favorite style.
The guitar will eventually transform the way you like it.
I guess I forgot to say something important with the previous post in the quote above.
I assumed that you found a bond to your 814 when you bought it.
To me, buying a guitar is a process of finding a guitar that sings to me.
The fact that you bought the 814 means that it captured your ear and heart somehow (or at least I thought that way).
This is why I suggested cherishing the time spent with the 814.
I understand how you feel because I had many similar experiences in the past.
From time to time, I found fantastic sounding guitars at shops and thought they are better than what I owned at that time.
Then I brought some back to home (exploiting 2 weeks or 30 days return policy). There I could do A/B tests under the completely same environment.
Most of the cases, I found the ones I already owned better sounding than the new ones. That was probably because I knew how to "speak" with the guitars I owned. I knew pros and cons of them so that I could adjust my playing accordingly. For new ones, sometimes I felt playing a bit awkward just like having conversations with newly met girls (exciting but awkward).
Of course, in rare occasions, I found the new ones clearly better than the old ones. In that case, I found trusty new owners for the old ones and moved on (much easier than filing a divorce following the above analogy).
So, if you can, bring the 914 home, assuming you get a good return policy. And do a fair A/B test. Good luck and enjoy the process.
