    my sound guy keeps telling me I should get a 'balanced' guitar cable...

    Questions:

    1. What is a 'balanced' guitar cable?
    2. What's wrong with a standard guitar cable (ie. $30 cable)
    3. Is there any real benefit spending $200+ on a guitar cable (ie. anyone had experience with these expensive cables)?

    1) I could be wrong, but a guitar won't output a balanced signal and a guitar amp wouldn't take advantage of it if it did, so I don't see the point.

    2) Nothing

    3) No.

    Your sound guy has been reading too many "Absolute Sound" articles.

    Just get a good cable, balanced cables might have merits in a stereo system, (I kind of even think that is a stretch), but for guitar it sounds like pure snake oil.

    happy with my $30 georgeLs,

    balanced cable has two wires in a twisted pair and a coax shield, good for low noise and low signals. build those at work, but not worth a couple hundred bucks for a guitar IMO. Can build those for a few bucks.

    i have two 10' switchcraft cables that i've been using since 1997. no lie. gigs, minor tours, practice, home, wahtever. it's been through everything, even rain (light misting, not a storm). i'll never buy anything else.

    Balanced cables only work on devices that have balanced inputs and outputs. (TRS)

    Guitars and guitar amps do NOT have balanced outputs or inputs. (TS)

    you should start looking for a new sound guy immediately.

    I paid 20 bucks for my Whirlwind cable back in '87, still use it on stage. It's been through hell, mud, rain, you name it. When I'm not wireless, it's the cable I use. Never had a single problem with it.

    what's your setup? are you running direct to the mixer or is your amp being mic'd?

    Bingo! (that's the geriatrics's version of FTW)

    AFAIK, the only guitars that can use balanced cables are the Personal/Professional/Recording Les Pauls which do have low impedance pickups. Good luck trying to find a low impedance amp.


    I tried balanced cables back in the '80s, and they didn't make a bit of difference in a high impedance circuit.

    What's the problem the soundguy is trying to have you fix?

    I think the sound guys comment would only be valid if you were trying to plug your guitar into something that had a balanced input, like a mixer or rack mount effect unit or something like that. In that case you would use the balanced cable but merge the conductors from 2 of the 3 balanced conductors to the "s" of the TS plug that goes into your guitar. but then your guitar signal would need to be boosted as most balanced inputs are line level or +4db, compared to you guitar output which is lower (-10db or lower). this cabling method is used a lot for putting higher quality effects units (like an eventide eclipse) into the effects loop of the amp, which is usually line level...

    That would qualify as a "balanced cable" [this thread's post], but it wouldn't be a balanced signal....so would would be the point?

    microphone cables are balanced they have two prongs and shield, but they are dealing with very long distances and low signals

    I am not electronic geek enough to explain why, but the signal quality is waaay better and less noisy when I connect my rack effects unit in the effects loop of my amp this way. lots of stuff on the Eventide website to read about this...

    I HIGHLY doubt that your amp's loop is balanced

    My guess would be, he's simply using a better quality cable.

    No, my guess would be he was trying to drive a balanced device with his unbalanced amp.

    By NOT tying off the unused lead, he would get the noise he mentioned because the differential amp on the input was being fed a null signal.

    By tying it off, he pulled that differential amp to ground, killing the noise [but also defeating the benefit of a balanced system]
