In the Feb 2204 Guitar Player, they were hawking a "Analysis Pro Plus
Oval Studio" cable for $299. 300 bucks for a 10' guitar cable! It even
won the "Editor's Pick Award" and was described as "Warm, full-bodied,
and liquis smooth," and truely "reference quality."

How do these people live with themselves?

LOL! I love how they always try to justify this BS with non-sensical
"scientific" babble:

Proprietary Hollow Oval Geometry

Why the unique conductor geometry of Pro Oval? Mark Markel and Qinwei
Sun, the chief engineers at Analysis Plus, determined that round cable
used in conventional speaker cable designs has high levels of current
bunching, skin effect phenomenon, and other frequency characteristics
that degrade signal quality. Rectangular conductors were a little
better, but these suffered high electric field values caused by sharp
corners which can also cut into and injure the dielectric when the cable
is flexed.

After many computer simulations, Analysis Plus found that a hollow oval
cable was the best design due to its minimal change in resistance with
frequency, plus other benefits. The company chose a flexible, braided
conductor rather than the conventional solid conductor, which is
susceptible to kinks and deformations with resulting signal degradation.
A unique woven pattern places every wire statistically as close to the
return current as every other wire for evenly distributed high-current
density and superior sound.

LMAO! Excuse me while I go flange my VU meters.

Guitar cable is an example of an inductive high impedance
source (the pickup) driving a capacitive load (the cable).
What would usually be trivial changes in cable capacitance
could make an audible difference.

I'm kinda surprised that there aren't more guitar cables
made up of low-capacitance cable and a switchable variable
capacitor load.


It's a completely different situation than line-level
interconnects.

Les Paul has been championing low impedance guitar pickups since at
least the early 1970's. He managed to bend Gibson's ear enough to
release the Les Paul Recording, the Les Paul Signature, & the
(original) L-5S models with low impedance pickups.

Sales for those models all tanked. Gibson even wound up re-releasing
the L-5S w/ standard high impedance humbuckers.

Part of the problem is that low impedance guitar pickups DO indeed
sound different -- so different that guitarists were baffled by the
sound of those instruments. None of their old tone settings on their
amps worked anymore. The "flaws" of a traditional high impedance pickup
have become deeply integrated into the idiomatic sound of electric
guitar; what makes sense as an "improvement" in theory is often at odds
with the aim of the musician.

If you wanted to feed a High Z guitar pickup into a Low Z mic input, I
bet you could use one of those inline hi to low Z mic transformers with
1/4" plug on one side and XLR on the other. You would be using it
"backwards" but it should work fine. You could then even use
standard mic cable. Only problem is having the somewhat bulky
transformer stuck on the front of the guitar.

Absolutely. Even connectors can make audible differences in this
sort of situation.

But, I am not sure that still justifies charging $30/foot for what is
probably an off-the-shelf bulk cable.

This is called a "passive DI box." It doesn't work all that well since
you can't make a transformer with a high enough input impedance to
make a typical pickup happy. For that, you need an active DI like
the Countryman.

Indeed it does, as do the facts.

Yep. The first time I actually tried this, I was quite surprised. Much
better treble. The numbers actually bare this out. A 2H pickup is some
inductance.

I just did a little SuperSpice simulation on an RG-50.

Pickup model as a 5k resistance with 2H inductance, cable into a 1Mohm
load, there was a 15db peak at 10Khz, 3db down at 15Khz, then rapid
rolloff. Doubling the capcitance/length moved the peak to 6.3Khz, 3db at
10Khz.

I don't think anyone can deny the audibility differences of such peaks
and rolloffs.

Do you have any idea of the inductance and capacitance of mics? I did
some runs with guesses, but it don't seem to be audible as far as the
sims go. You need about 100mH to get a decent audible difference, but I
don't think mics are going to get much past 1mH, if that. Its hard to
get the data, and I havent investigated much on this before.

Yep.

Those that keep questioning you and me seem to belive that we are
denying *all* differences, just because we claim that *some* differences
are not audible. The err..difference, is that we know when there is a
difference and when there is not.

Did you take into account the triboelectric effect of the coax
dielectric? Those kinds of cables are made for low-impedance
use where they are fine. OTOH some of them make excelent
microphones at high impedance.

And all the ones I've ever seen are way too stiff for any
e-guitar player I've ever met.

Well, yes, but that wasn't really the point of the bit of the
discussion.

What I was doing was highlighting where cables do actually make a real
difference to the sound, and where such differences are firmly backed up
technical considerations such as frequency response. This is to contrast
the condition where people claim that speaker cables open up a new world
of realism, rather than just opening up their wallets.

OTOH, low-capacitance cable is easy to find and spec. The only trick is
sourcing a neophrene jacketed version.

PVC jackets don't really hold up for most guitar players.

I assume the impedance is trdaitional because of tube amplifiers that
naturally had a high input impedance, and the higher inductance pickup
had higher output voltage hence lower noise.

Isn't it about time guitar pickups were wound at a lower impedance, so
they'd work with a mic input and be relatively unaffected by cable
capacitance and microphony? Mics managed that change years ago!

It's been done, but they didn't go over that well. Most serious guitar
amps are tube and a low-z pickup had to be interfaced properly to sound
normal.

Not that it has anything to do with impedance, but maybe even high
impedance pickups would hum less if they were connected with
two-conductor shielded cable to a differential input on the guitar
amplifier.

I recall seeing one model of the Les Paul Recording guitar and
companion amplifier that had XLR connectors on the guitar and
amplfier, but that's about the extent of it. I think that most
low impedance pickups (Ol' Chet had some made at one time, too) were
connected with an unbalanced. Probably because the guitar players were
always forgetting their chords. <g>

When Eric Johnson played the Alembic I have he liked some things about
it, but not that it wouldn't feed back.

OTOH, my brother spent about fifteen minutes working with it to mimic an
acoustic guitar sound and damn near matched my lovely J200 into a good

What do you mean by this? As far as sound goes, if the connectors are
mechanically sound, then the connecters make no difference to the sound
whatsoever. Contact resistance is way too low to have any effect. Sure,
if the contacts are corroded they may be a problem, but any old clean
contact will do fine.

Try measuring the shunt capacitance of a 1/4" phone plug. With a 1M
line, it's not negligible.

I doubt if its more then about 10p, and is totally insignificant
compared to the cable capacitance. Guitar cable might be around 100p/M.

> --scott

Oh dear...

The line isn't 1 Mohm. That's only the input resistance of the amplifier
input, with should be as high as possible. Its the source impedance that
matters. A guitar source might be 5k in series with 1H-2H. At 10khz a 2H
inductance will give a 100k impedance.

Indeed, one could make the input resistance of the amplifier 100M giving
a 10p HF corner of 159Hz! This comer is of course completely imaginary.

Oh dear...this is like taking candy from babies, with their hands tied
behind their back.

If you would like, you can download my SuperSpice and actually do some
simulations with cables and stuff. The advantage, is that you can check
things out before making comments in NG's and then be sure that they are
