The pedal you have Scottyee is an inline volume pedal. There are two varieties of FV50; L or H. As the names suggest one is for Low impedance signals (such as keyboards
So then is the Boss FV50L the right/wrong pedal to be using with Tyros 4 for controling organ voice volume and expression? Should I be using a Yamaha FC7 instead?

Thing is that when I connect one of the Boss FV50L's 2 outputs into my Tyros 4's footpedal controller socket #2 it seems to work at increasing and decreasing the volume of whatever specific part(s): RH1, RH2, RH3, LT, I have assigned to foot controller #2. How does the Yamaha FC7 function differently?

My Boss FV50L includes this minimum volume adjustable knob too.

After what Sweentech1 posted, I'm now confused whether the Bosa FV50L I'm using is adequate or if need to puchase a Yamaha FC7 now. Please advise. Thanks. - Scott
