Suggestions on a DI box for an Electric/Acoustic guitar?

I don't feel like I'm "qualified" to answer this.  But at church, and in other live situations that I've been involved in, acoustic players almost always seem to use a DI before the PA.
We recently began going direct with all the electric guitars at church also, and we're all (electric and acoustic players) using some sort of DI box.  Mine was about $50 from Sweetwater, and it's the same as most of those that I see on stage.  It's a Whirlwind 1-ch Passive Instrument DI.  It works fine for what I'm using it for, cutting out some single coil pickup noise I was getting from my Jazzmaster.  It also seems to reduce the overall signal going to the PA.  Are they supposed to do that?  I'm not sure, but it did the same thing at band practice when I tried it there.

Another guy bought an active DI with a 20db boost, but it seems like that's too much to be useful, and he doesn't use the boost.  So, why pay more for an active DI with a boost?!  My feeble mind would like to know!  Maybe it works better with acoustics.  Maybe someone here can answer that.

Do you know the impedance of the source and the impedance of the destination?
If you don't....it's homework time.

I like Radial DIs.
Their passive options have good frequency response but have rather low output.
I often stick them on the bass because the transformers go way down into the basement.
They need a lot of gain which is not a problem if your mic pres are quiet.

There are many options for DI boxes. It depends upon how much money you're willing to spend. I also have a 2nd generation 18i20. It does not have tons of gain and may require either an active DI or a gain booster of some kind. The Royer Dbooster or a CL-1 Cloudlifter comes to mind but, if you have to buy a DI AND a booster there are a number of companies who make designated guitar mic preamps for less that what a DI and a gain booster would cost.

Using acoustic guitar pickups in a live situation is the only way to go BUT, in the studio you will almost always get a better sound using a microphone on your acoustic guitar. Even if it's a dynamic mic. I have recorded some great sounding acoustic guitar tracks using a SM57, SM58, or Senheiser MD421, microphone. And if you have one, a condenser mic will usually sound even better. To me, the only good-sounding direct acoustic guitars are electric-acoustics that are purpose built for that and that only like the Fender Acoustasonics or something similar.
