Thank you to Edward Carson at Tone Shop Guitars for installing the patent pending QiJack from Analysisplus Cables. The jack expands into an oval shape over the guitar cable to give a consistent grip which also allows for two contact points for the Tip (+) and Sleeve (-) for a better tone and stronger signal. Another genius idea from these guys! https://www.analysis-plus.com/…/home-aud…/connectors/qijack/
