I bought these patch leads so I could use a Boss NS-2 Noise Suppressor with a new Boss BCB-30 pedal board - I needed a patch cable long enough to go from the third pedal right back to the first one (the NS-2). They certainly do the job, but the plugs are quite loose in the socket. They make perfect contact, but would pull out of the socket with little effort. A good entry-level product, but I will upgrade to better cables in the future.
