Light Lead, a company from Essex in the UK have just launched their Kickstarter campaign
This could well be the answer to long cable runs and cable drop out for all electric and plugged in acoustic instruments. Light Lead does not use wire to send signals it uses analogue light. Analogue light is not affected as it travels down a fibre, where as electrical signals in copper wire add all kind of "mischief" to the sound.
Light Lead delivers Zero Loading, Zero Capacitance, Zero Micro-phonics, 100% Isolation from electrical shocks, Consistent and reliable sound whatever the length, No more crackling cables.
Take a look at their site for more info and if you see the light at the end of the cable get involved. We will have a full review of the prototype on PTE next week.
