Boss FS-6 Footswitch  

If you have a BOSS GT 6/8/10 then first get an extra expression pedal. If you still want more options then get these. Am very satisfied with these footswitches. What they don't tell you in the manual is that you need stereo cables to use both switches simultaneously. So you'll have to get one if you're buying this.

I bought the BOSS FS-6 Dual Foot Switch to use it with my BOSS GT-10 Guitar Effects Processor. This is a great compact unit that provides two switches  that can be independently set to Latch or Momentary function with selectable Polarity. For Latch function, Polarity will only change when the LED will lit (either when in CLOSE position, or when in OPEN position). But for Momentary function, Polarity allows the switch to be set to either Normally OPEN or to Normally CLOSE, great versatility! The FS-6 has been extensively criticized for not having an ON/OFF switch. This is not important at all, in fact it is better that it doesn't has an ON/OFF switch and I'm sure it was deliberately designed not to have one, as you will see. The FS-6 will stay OFF (even with the included 9 Volt battery in place) until a plug is connected to "A", "B", or "A & B" connectors. You don't need to remove the battery when nothing is connected to it. The "POWER" LED will not lit indicating that the unit is OFF so the battery will not drain. This thing basically turns ON automatically, preventing any damage that may be caused to your equipment if it had and ON/OFF switch and you accidentally forgot to turn it ON. Why would you want to have an ON/OFF switch when the FS-6 was so well engineered? This safety feature may also explain why there is not an AC power option available. This is a great piece of equipment. And it enhances the functions and flexibility of my GT-10.

I use this thing with a Boss ME-50.  It works just as advertised, and the switching options on the back give me the ability to use it for all kinds of other things.  I've had it for like a year at least, if not two.  The only problem I've had with it is that I accidentally broke the plastic battery cover (it would be nice if someone could send me one lol), but that's nothing that duct tape can't fix.  I'd buy another if mine broke, but with how Boss makes their pedals, I doubt it will break.

Good product. But, the momentary setting operates like a latch setting. And the latch setting operates like a double latch setting. Wonder why.
