however, when i connect my electric guitar (Lace

1 & 2 of the H5 with gain only at 5 of 10, i get a good sound and strong
signal, seemingly the same as when they are connected to an interface (in
this case a Zoom U-44) that supports Hi-Z connections.
now while i do not yet have a good understanding of Lo
vs. Hi-Z, i have
read various posts about it. they seem to indicate that the passive guitar
signal would lose some frequencies with this kind of connection and thus
this setup is undesirable.
A Di guitar sound is an effect if it is through a Di box or not. If you
like the effect, good stuff. (use your ears is always good advice)
Personally, I have found that I like the sound of an electric guitar
better if there is a speaker somewhere in the chain. Even for clean
sound. Amp emulations can be quite good at rebuilding sound to sound like
an amp, but then I add a speaker to the chain (even with a solid state
amp) and there is some difference that I like the sound of.
In the same way, there will be a difference in sound from one preamp to
any other. Either you like the sound or you don't.
However, electric guitars and electric guitar amps were designed together.
There was no recording or Di, it was all live performance. The guitar does
not have an impedance that is a number, it may have a DC resistance or 5k
to to 15k or so, but it also has an inductance and capacitance (and the
cable changes that too) and the matching amp has it's own input
resistance, inductance and capacitance as well. The same guitar through
any two amps will sound different because of this even if they have the
same dc impedance. The inductance and capacitance will change the
impedance with frequency. So any guitar/amp compination will already
provide some filtering before the sound gets to the preamp.
The amp itself further changes the sound from input to output and of
course the speaker/cabinet is tuned in the same way the body of an
acoustic guitar is tuned. So the guitar/amp/speaker/cabinet combination
providss a complete sound. The Di can't give the same sound though some
modeling comes close.
This why I say, if you like the sound nothing else matters. Guitars and
basses are different too, a Di is much more common for recording a bass
than a guitar where high frequencies are in general not wanted, though as
a bass player myself, I like the sound of at least some high end on a
fretless as it accents some of the glides.
Piezo pickups are different again. I use them on both acoustic guitar and
manolin. They sound just bad into my mixer or just about any Di box for
that matter. 1 Meg is not enough. That is why so many of them have built
in preamps.
I have used electric guitar plugged direct into a mixer and been happy
with the result when looking for a "clean" sound. For anything with a bit
of roughness or more, I prefer an amp.
