I bought a Boss FS-5 switch years and years ago, and its still going strong! However I needed the same type of switch for switching the FX on the PA on and off, but this time with a indicator light to show if its on! I always look at the Thomann web first, as its so easy to find products quickly, and its the cheapest.
There are hundreds to choose from, but when I saw the Boss I was over the moon, knowing that it was a strong steel case and well built. The red light indicator is bright enough to see when on stage in the dark, but not to bright. There's a small switch at the front to change the switching phase around. Having the light on when the FX is on works better for me. Two batteries inside with easy access, and already in place. These switches are really good and at a fair price, also I know they'll last for years. 10 out of 10!
