Location: Utah | There are only a few passing references to the stereo output on the factory website, so which models have stereo? All Adamii? Certain preamps only?
If the guitar has the stereo feature, can it be bypassed simply? |

Location: NJ | the early gutiars had two out put jacks one stereo one mono, I don't know if any of the guitars are stereo now. I find it a rather useless effect. |

Location: East Wenatchee, WA | My 1537 has the stereo with string 1,3,5 on one channel and 2,4,6 on another. I agree...worthless effect overall, and I always use the mono jack.
I did try it once in the Mackie board, but you can't leave them panned hard left/right or it twists peoples heads off when you strum a chord. Lightly panning L/R is okay, but slight chorus or delays are much better in my view than stereo.
I do like the piezo in my Carvin DC400 and putting the piezo and humbuckers into seperate inputs on the pa gives almost a two guitar feel. Can't wait to play with it on my LB75P that is on it's way. |

Location: Colorado Rocky Mountains | I tend to prefer using the stereo feature of both my 1651 and Adamas II over the mono feature, but not on my older solid bodies. The roundbacks feature the EDB strings on one channel and the AGE on the other. Split through multiple amps and/or a stereo PA system, it really fills the room with a full sound that I personally prefer, like sitting in between two guitar players playing different parts to the same song. The sound is even better when using a headset. With the solids, the stereo split is between pickups and the distinction through a PA is barely noticeable IMHO. That said, the effect really is more of a novelty than something useful. I’ve used it in a live performance for only maybe a half-dozen occasions that I recall. The equipment requirements for stereo performance are burdensome. |

Location: CT | Yes, the older high end models: Adamii, Legend & LTD, Anniversary, Custom Legend. The Balladeers & such only had mono. I've owned my Custom Legend for about 23 years now, and never used it stereo once. I used to own a stereo Yamaha 12 string, and never used that in stereo either. |

In electronics, the plug is the outie and the jack is the innie.
YMMV |

Lo z means low impedance, doesn't it? What's the difference between impedance and resistance? |

I start work at 6:30am, but I live an hour away. Getting up at 4 gives me a chance to wake up before I hit the road.
Of course, I start nodding off around 9:30pm... |

I expected to hear a paragraph statement with a math equation thrown in to impress... boy was I in for a surprise. The instructor - don't quote me but I believe his name was Al Grundy (it was ages ago) went into a 45 minute lecture on the intricacies of these 2 terms, starting out at about the bronze age up to today. Every one in the class wanted to throw things at me. It scars me to this day... :( |

Resistance is what it sounds like. In electronics you could consider it similar to pipe diameter in plumbing. If you make the pipe smaller, less water flows through it and it has a higher resistance to flow. Resistors similarly reduce the amount of electrons flowing through them.
Reactance is similar in concept, but it is frequency dependant. A circuit with either capacitance or inductance will tend to allow some frequencies to pass easily and others to be blocked. Such circuits also change the phase of the signal, which can make the quality of the sound different.
Z is impedance, and it is equal to the square root of ohms squared plus reactance squared. Z= square root of (Rsquared + Reactancesquared). A circuit or cable can have a little or a lot of inductance or capacitance, plus it can have plain resistance.
So, a low impedance circuit allows more electrons to flow than a high impedance circuit. But you have to also talk about what frequencies are involved and the characteristics of the circuitry.
From a practical standpoint, you have to match impedances to get a good signal. AC signals tend to reflect at discontinuities in impedance. If you have a 50ohm impedance cable, a waveform will move down the cable uniformly until the impedance changes. If you plug it into a 10,000 ohm impedance, the signal will partially reflect back down the line to the origin. If the impedance at the origin is other than 50 ohms, it will reflect again, like a wave in a bathtub back and forth, polluting the original signal.
So your cable should be matched impedance to the source and the destination. Your source should also be matched to the destination.
This is an AC phenomenon related to the reactance of the cable. In the world of resistance you don't have the reflection problems and the sources don't have to be matched. If the resitances aren't matched you will get power splitting or voltage drops which could cause signal degradation, but other times you mismatch on purpose. |

NIGGLING DETAIL ALERT ON
Waskel has kind of misassociated two system characteristics. While the XLR is lo-z and also low noise, the two are not necessarily synonymous. Nor are they necessarily causitive. The XLR is low noise because it is a differential system. It has two signal lines that are equal and opposite. At the receiving end you sense the difference between the signal lines to create your output. SInce environmental noise will affect both lines equally and in the same direction, it gets subtracted at the input to the amplifier. To view this in a very loose mathematical sense you might think of it as follows:
Coming out of your guitar you have two signal lines. Let'e call them +music and -music. At the amplifier you will have noise contributions added to each line so now we would have:
(+music + noise) and (-music + noise)
At the amplifier input we take the difference of the two signals:
(+music + noise) - (-music + noise)
Regrouping terms (sounds like arithmetic class doesn't it) we end up with:
(+music - -music) + (noise - noise)
More clearly this becomes:
(music + msuic) + (noise - noise)
The end effect is that we have the music signals on the wire addiing together and the noise sinals cancelling. Very common technique in many engineering/mathematical applications.
To be excrutiatingly accurate, lo-z circuits do tend to exhibit lower thernal noise, but this is likely to be quite small in comparison to environmental noise.

Location: Boise, Idaho | I was with flysig until right after, "I'll take a stab at this one." Stabbing I understand. I also know that the XLR function on my amp has less noise, except for when I plug in the Ute and it picks up a radio station. Can one of you electronics geeks explain that for me? |

I said XLR = cleaner signal. I made no statements concerning why, did I? Most guitar players, they could care less why XLR is cleaner, they just know it is. Especially over long snake runs, low-z compared to high-z.
The other piece Flysig had. Low-z (assuming everything is matched correctly) gives you a wider frequency range than high-z. Now, I know Ovation preamps are supposed to be optimized for high-z, but I can still hear a difference on a house PA between the 1/4" and XLR from my Adamas Optima running over a 100' snake.

To say they could care less, indicates they care at a level, however small, that there is a lower level of care that they could aspire to. ..I care 'X' amount.., but could care less than that amount.
If they couldn't care less, they care the absolute rock bottom amount. There is no amount less that they could care. ..I care ZERO amount, and I can't possibly care lower than that amount. |

Which models have the stereo output?
