I highly recommand rainwater sound (rainwatersoundllc) on ebay. The guys make awesome cables with gold neutrik connector and mogami cable for a really good price !! I order all my cables for my rig there. I had him to make me a custom cable for my jp bfr, a 20' cable with an angled str connector to a Y. It cost me like 35$. Then I programmed my fx unit (line 6 pod hd pro) to select between the piezo and magnetic for the choosen patch so i don't have to touch the p/m selector.
The Planet Waves cable above, while it has a good price, there are some drawbacks.
1. There are 2 cables drawn together from the start of the 1/4 inch stereo plug and go the entire length of the 20 foot cable terminating at 2 TS plugs. The good is that you can seperate the 2 cables and make them spread as far apart as you want. In my case, one end goes into a Fat Boost at the bottom of my pedalboard and the other end goes into my Fishman Aura pedal at the top of the board. The bad; the cable is heavier since it isa essentially 2 cables and it doesnt moove well on stage and it tangles and twists very easily.
2. The TRS plug is straight. I find that the placement of the the guitar's output jack prefers a right angled cable. If you put your guitar on the floor or a low stand with a straight jack in it, it is very easy to damage the jack or the PCB that it it is attached to. The ProCo above is much more expensive but is a far better choice. Just my observation from having owned a Planet Waves version.
Nice little quasi review there scream. I used the P. waves cable, but I've personally never had an issue myself. If you're leaving cables plugged in, definitely would be a concern I suppose.
