Jack is the first plug in device which turns any guitar or amplifier into a WiFi device for wireless playback and studio quality connection to unmodified PCs, Tablets or Smartphones. Putting the power for low-latency WiFi at the disposal of musicians everywhere, Jack does away with wires and can connect to amplifiers or even PCs for recording, editing or uploading. The articulating Jack is said to fit most electric guitar and bass models. I don't usually get excited about Kickstarter projects but this one shows a lot of promise. Check it here.
