Re: help an electric nerd/nut learn about what kind of acoustic electric to look for
For a pure acoustic, nothing beats a great Martin. I've owned a Martin since 1973, and now have several. I have a new HD-28E Retro, and it is AMAZING. And plugged in, the F1+ AURA is simply the best and by far the most natural sounding pickup I've heard. Ever. But, it's a $3K guitar, and it should be fantastic...and it delivers.
I also have a 2002 Taylor 710-CE. Mine has the Fishman preamp, and I prefer this over their ES. ES is fine for fingerpicking, but I find that it breaks up with hard strumming. And acoustically, the guitar is no match for any of my Martin dreads.
I also have a Takamine EF381 12-string, and it is a fine mid-priced guitar. Totally exceeded my expectations. The CTB-4 preamp is really great. Tak builds some really terrific acoustic electrics...don't count them out. There's a reason why so many touring groups use Takamine.
I recently tried one of the new Yamahas; I didn't play it plugged in, but it was very good acoustically. Not giving up my Martins, but it was a great value. Sorry, don't remember the model. Another brand to look at is Breedlove. I've had good luck with Ibanez instruments too, I have an Artwood acoustic-electric, and to be honest, it sounds as good as my Taylor. Tremendous bang for the buck.
The thing to do is to play a lot of guitars, and find the one that speaks to you. And be sure to budget for a good setup from a luthier.
Good luck!
