Some people do, but it doesn't really work that way. When you hook up
a DI backwards, it's acting as a step-up transformer. When you connect
a line level signal to the XLR end of the DI, it comes out the 1/4" jack
end at a level well above that of a typical guitar pickup. Of course
you can always turn down the input to the DI so that you're putting
something close to mic level into the "mic" side. You'd eventually
figure that out.

What you really want is a transformer that's close to a 1:1 ratio.

A hundred years ago Mix magazine did a shootout with all of these DI's,
the Radial won most of the categories hands down, oddly enough a RAPCO
box took second in a lot of the categories. Ampeg however is marketing
an affordable tube DI these days.

I guess I read too much into your original message. Most people who
ask a question without a full explanation are looking for a one-box
solution.

In my (admittedly limited) experience with recording an electric
guitar direct, once you get over the bottom line junk, the choice of a
DI is relatively non-critical. Unless it's for a very special effect,
you're not going to use the direct sound without some significant
processing so as long as it comes close to representing what the
guitar is doing, you can work with it.

Bass is a different animal. With the right combination of bass, DI and
music, you can get a usable sound directly off the pickup, and it's
almost always useful to augment the sound of a mic on a speaker.
This is apparently where the Evil Twin DI really shines.

When you play a DI guitar back through an amp, it'll start sounding like a
guitar again, but since there are no vibrating strings to react to the
sound of the amplifier (and no player, either), the amp will respond
differently to the playback of a direct-recorded guitar than it will
to a played guitar. So you can't get your sound back by simply setting
the controls like you're used to.

Radial stuff is good quality. If it's easy for you to buy, it's a good
place to start. But this isn't a make/break decision. If you can use
another decent mic preamp, you might look at one that has a good rep
as both a useful preamp. That's getting two for the price of one,
a potentially good deal if you can use the two.

Actually, I think I would probably use the same DI for recording and
reamping. I would also ensure that the levels going out matched the
levels going in. This way, I would have the best chance of feeding
the guitar amp something close to what it would have received if
the guitar had been originally hooked up to it.

As guitarist, I have experienced how dramatically different the amp
interacts with the guitar depending on what you feed it. Guitars
with active electronics, passive electronics, single coils, and of
course the can of worms that effects pedals are...it is very important.

With that said, after getting an output from tape that matched the
input as closely as possible in terms of level and impedance, I would
spend some time trying adjusting this output level and seeing how
the amp "likes" it. I guess one of the purposes of reamping is
having the choice later between different amps and effects.

Right, and the 1/4" output can be switched to loop-through, or provide
another line output in addition to the XLR out. The ET offers up to 36
dB of gain.
