I have been playing guitar for more than 20 years and I have a very good quality gear, so, any low quality piece of gear (pedals, cables, ...) would ruin my sound quality. I wanted a pedal board connection cable that does not add noise to my rig, and these cables are the answer.
There are two main features about this cable that I really like to highlight:
1) I bought 2 pieces of these cables to add 2 new pedals into my rig. I am very pleased because I noticed that after adding these pedals using this cable, the sound quality didn't change at all! There is No noise, and the tone didn't get muddy or darken, unlike other cables that I had tried. So, I am considering to change all my pedal pedal board connector cables with these nice cables.
2) The cable IS flexible (you can bend and shape it as you like), but once you shaped it will remain in that shape. For example, if you are connecting two pedals that the output of one and input of the other are both located on sides of the pedals, the cable gets the U form and REMAINS in that shape. For pedal board it is a very good feature, but if you are trying to buy it and use it all the time for different applications, I don't recommend that.
Any way, I am very pleased.
Thank you Thomman :)
