This is a very high quality jack plug. It looks fantastic on your pedalboard and really gives off a professional high quality air about it. The jack is easy to solder, weighty in the hand and passes audio signal in a transparent and high fidelity fashion. When coupled with the right quality cable, this jack should give you a product that is many orders of magnitude greater than products you can buy in the "premium" end of the market. Its nice that HICON offer such a professional product for the DIY market. Finally the integral rubber strain relief is an inspired and very welcome touch.
