    Worlds First Analogue Optical Guitar Cable - On Kickstarter NOW!

    Press Release July 2015

    LightLead™ Launch Kick Starter Campaign

    London, 2nd July 2015 – Following on from the LightLead™ successful debut at the Winter NAMM show, inventors Iconic Sound Ltd, have just started their sixty-day Kickstarter campaign -

    PR_Light_Lead_Launch_Kickstarter_Campaign_(TV).pdf

    Https://www.kickstarter.com/projects...al-audio-cable

    The LightLead™ is the world’s first optical analogue, jack to jack, musical instrument cable. Its fully patented technology offers musicians a lead with zero capacitance and loading, resulting in a more precise, perfect, dynamic and crystal clear sound. The LightLead™ is ideal for guitarists, bass players, and violinists, in fact any electric stringed instrument where a lead is required. Here are just a few of the comments from industry experts:

    “Iconic Sound’s LightLead™ may be the first substantial innovation on instrument cable technology since, well, the cable was invented.” HarmonyCentral.com

    ‘There is not a guitar player out there who won’t want one of these.’ Mike Chapman, record producer and songwriter

    ‘I have never had a better signal from a guitar, this lead is nothing short of a paradigm shift in cable technology.’ Producer Liam Howe (Lana Del Rey, Elle Goulding, Adele)

    ‘It definitely makes your guitar sound clearer and fuller. It’s a clever bit of kit.’ Grammy award winning producer Rik Simpson, currently recording the forthcoming Coldplay album, using prototype LightLeads™

    Using traditional copper guitar cables has always come with a significant risk of grounding problems. Over the years many musicians have been badly shocked, electrocuted, and even in some cases of death. A well-known example of this is Keith Relf of the Yard Birds (later becoming Led Zeppelin). Relf was electrocuted and subsequently died on May 14th 1976 as he was playing electric guitar with a badly grounded cable in his basement studio. Being made from non-conductive fibre optics LightLead™ completely eliminates this risk of an electric shock through the cable.

    There is a strong team behind this product. David Holmes is a sound engineer, programmer and keyboard player and Danielle Barnett is a professional musician, businesswoman and entrepreneur with more than twenty years experience in the music industry. The new member of the team, Damon Waller, is the ex Managing Director of Orange Amplification and guitar player who brings more than thirty years music industry experience with him.

    It is now time for the next generation of musical instrument cables and your contribution will help launch a new revolution in the pro audio arena. The Limited Edition LightLead model that is available on Kickstarter is exclusively for our backers, and will not be on general release. Please spread the word and tell your friends.

    The future is light!

    If I'm going to have to put batteries in something, it's going to be my wireless.

    Pros -
    electrical isolation, so no more chance of electrocution
    no capacitance if you like that

    Cons-
    no capacitance for those who don't like that
    four AAA batts with 18hr life. WTF? Like Dude said, if you're going to have batteries, why not just ditch the cable altogether and go wireless
    durability- how many times can you step on it, or roll a rack or speaker cab over it?

    Yeah, except for all the ones who actually want and seek out capacitance in their cables. Some would actually hate this thing.

    This will probably come to fruition and find a niche market, but unless it's more durable than standard cables, and they find a way to drastically increase battery life, it's certainly not going to take over the market.

    Let's Not Forget The <BIG> Question...

    Especially for us types who loiter about here:

    What do I do about it WHEN it breaks? I can fix my regular cable on a gig if need be. Can I fix this thing myself? No, buying spares is not an acceptable repair plan. The ease of repair on the fly is worth any supposed ill effects from cable capacitance or signal degredation. I play a Tele thru vintage Fenders with a chorus or flanger. My audiences would probably LIKE some hi-freq losses in my signal chain, anyway!

    This screams "great for studios." Not so handy as a bar weapon.

    And yes, Analog is GOOD!

    From the Kickstarter page -

    Just to make you comfortable with your new optically transparent sound, we have also added some 'Light Gears' so you can roll off any frequencies you don't like. muddy old cable (...if you really want to).

    which I think means some degree of capacitative loading can be switched on to the guitar, in order to facilitate obtaining the regular response.

    "Light Gears" - that's funny and very clever.


    I wonder about the linearity.

    Not that linearity was ever an objective in guitar amplification, but it does have to be right kind

    To get a LED /photodiode coupler to be linear you get a matched pair of these fabricated on the same chip and use one in the feedback path to linearize the other. I did this for an experiment and I recall I got something like ~1% THD, not great. In this case they can't have exact matched pairs so I assume there must be some signal processing to attempt to compensate. It has to be less than ideal.

    Seems you'd have lower power and better quality just bufferring the signal at the guitar output. Batteries would last for months. THD next to zero.

    The suggestion that it will "help launch a new revolution in the pro audio arena" is perhaps a little ambitious.

    It's nice to have something new on the market, but time will tell. I guess if the 'A' listers start using it then they'll sell plenty. Remember when digital modelling amps would revolutionise the amp world? They established a market share and gave people more choice, but didn't convince most tube amp players to ditch their gear.

    What happened to optical pickups, too?

    There are (and have been for a few years by now) two way fiber optics audio links for live audio use.
    Think replacing a wrist or arm diameter multi copper pair snake by a much thinner and stronger one.

    So these guys are not that revolutionary.

    Hi,

    Thanks for your comments, I have a new video out that might answer some of your questions.

    I agree wireless is great for convenience, but if your passionate about sound a LightLead will be consistent with your guitar,bass, or any semi-acoustic instrument all the time.

    Do you record with your wireless system, or use a cable.

    Just curious

    Ok for those who like capacitence in the signal chain varying every time they change the cable or strings then a cable is fine.

    As for rolling cabs a stepping on our LightLeads, they are not your everyday CD player optical fibre. Its a custom fiber and is very resilient.
    The difference is when your break the tiny copper wires in a cable capacitance adds up...In a LightLead if you fractur the fiber it wont affect the frequency range being passed through the fibre.

    Did you see our new video on the impedance feature?

    We like to offer the "snake oil" types to try the LightLead for themselves. They usually decline but....
    Perhaps i could pursued you to try?

    The optical cable part of LightLead is detachable, replacement cables range from £15 - £30

    Our prototypes are 3 years old now and have been on tour with Peter Gabriel (SO tour), 6months in the studio with ColdPlay recording their latest new album, constantly dragged around NAMM by Ola Englund, Hadrien Feraud and Dean Brown, and lastly at Air Studios UK where Toby Pitman really put it through the mill.

    Have you noticed when you buy a new cable or even new strings how much brighter your sound is? Is that a bad thing.
    We are not trying to change the perfect sound you have, but give the the very best from you through your guitar or bass or any semi-acoutic instrument.

    Yes we like "Light Gears" too, Johnny from ColPlay said "im playing through lasers!".

    Linearity is not an issue with LED's and we don't use any compensation, however we do have a clever patent that keeps our diodes in check.
    I think there is a powered cable somewhere on the web. Or their are the buffered pickups of course...Its a choice, and now LightLead is here.

    To me, your video just seems to demonstrate the benefits of a buffer between a guitar and lowish impedance input; the optical aspect of the connection seems immaterial?

    EDIT: As you are happy to get geeky with scope and sig gen, and a concern has been raised regarding linearity, how about demonstrating your system's signal transfer accuracy over a range of frequencies / signal levels?

    The above doesn't make sense to me. I can't see that either different strings on the guitar, or a broken strand or two in a copper cable's conductors, will have anything beyond a trivial effect on the cable's capacitance?

    Sorry to be picky, your product looks really good!

    Yes the buffer is a first line of defense, and of course some guitars already have powered pickups. The optical aspect of the LightLead is to ensure that the cable doesn't degrade over time and also avoiding ground loop issues.


    I will do a DI comparison video for you.

    Hmmm. Not degrading over time. Maybe a rotating magazine of stock cables could do that at lesser expense.

    And any method for breaking the ground loop - including setting up your amp correctly - will do that. It would be more interesting if this kept the guitar pickups from sensing the ambient 60Hz magnetic field while still sensing the strings. There are already some optical string sense pickups, so don't go running to the patent office with that.

    Now if you could just blast out an omnidirectional coded stream of light pulses coded to send guitar signal to several receivers on stage, with coding so that the guitar would not need either a wireless RF rig or a cable of any sort at all... OK, wait, I have to run to the patent office...

    Amazing!! Who would ever have guessed that someone who villified the evil rich people would begin happily accepting their millions in speaking fees!

    Oh, wait! That sounds familiar, somehow.

    But seriously folks, the problems with an analog (analogue for those of you further east) optical cable are still tied up in that you need to put a lump of electronics in the guitar. Once you cross that boundary, you can convert to pushpull differential pairs and kiss ground loops goodbye that way, too.

    Neither of these solve the issue that guitarists LIKE the interaction of the guitar pickup and controls with the amp's input impedance, so you have fake the amp input impedance out at the guitar to get that back, in all of these schemes.

    But sure, makes a great way to harvest funds from crowd sourcing.

    I'm down on crowd sourcing. Search "crowdsourcing scam". Or just "Devi Ever".

    If this is what you meant, Crowd Sourcing the labor market, then it's very depressing.

    As far as the Codemus novel, I spent several years, tethered to a Blackberry, expected to respond 24hrs a day, meetings at 1am to suit Far East customers and generally having my life controlled by it. That is why I now do my own thing is a quiet rural haven. I went to the park and stayed there
