I just got this pedal and it works fine,although I did have to find a cable for it.You would think that they would include one with it.I also had to by the power supply for my BR600 (slso not included), and that has a ground hum.When I contacted Boss they said I may need a Power supply filter.I guess they expect us to make their product work .

I grabbed the Boss FS-5U Footswitch for use with my Boss BR-900CD, and it rocks! The compact metal casing and rubber bottom is very sturdy! The switch itself is made of plastic, but is still better than the Roland DP-2 that I was considering. I had also considered the Boss FS-6 dual pedal, but that model requires batteries or an AC adapter. The FS-5U requires neither, only needing a single 1/4" TS (mono) cable. The various foot switches that Boss makes can attach to the sides of one another, which is very convenient! However, this does create some sharp metal edges that can scratch other gear, so store it carefully. This is an excellent no latching footswitch, and I highly recommend it!

This pedal, with it's polarity switch, allows connection to all kinds of gear, drum machines, amplifiers, whatever takes a quarter inch input. It's rugged and dependable. Cool.

The FS-5u is a fine addition to the Boss DD-5, and is small enough to easily fit in small spaces on nearly any pedal board.
