Boss FS-6 Footswitch

Take two FS-5 footswitches, weld them together and add an option for "latch" and "non latch" operation for each pedal. Yes, you got it, this covers every need you can come up to. And it's sturdy and reliable too. Good solid pedal, it requires a 9V battery to operate. No connection to a power supply, though. If you want o use one, you'll have to work your way around the 9V connector. It's the only negative point to this pedal...

I bought it a long time ago, when I was starting playing the electric guitar as an addition to my Boss Katana 50 combo amplifier. But I understood, that I have never actually used it. Later, when I have bought my first looper - the RC-1. I have suddenly spotted that in the looper was an input for the footswitch. That was the moment where I understood it's usefulness. So, if you want to used it with your amp, go ahead. If you want a looper, don't be an idiot like me and buy the RC-30.

only can use with 9v Battery, but works great

good to upgrade my RC-3, make it easier to use and also can be used as two expression pedals for tap tempo or what ever use you can do whit it

to use with boss delay pedal

I usually use this for my delay pedal and loop pedal.
