If you're playing keys or organ, it is necessary to use a volume pedal. I didn't want to spend too much money, but I also wanted to have a good quality. After trying some pedals at Thomann Music Store in Treppendorf, Germany (It's like disney land for musicians!!) I chose the Yamaha FC-7. It has a wide base for big foots and its surface is anti slip with the naps on top of the pedal. Also the underground of the pedal is anti slip, and that is very important for performing on stage. The cable looks a bit weak, but it works for more than 3 years and there were no problems. What you have to know: It has no zero point! But that's ok for me. I don't play if I don't want to have sound.
I used to use a simple stereo volume control pedal between my synth and the amp. It wasn't expensive and it did the job - until the mechanism broke. I invested the extra money in the proper Yamaha expression pedal and have not been disappointed. 1 - you can configure what the pedal controls - not just volume. 2 - the construction is very robust and reliable. If you have a Yamaha keyboard, spend a little bit more and get a better solution.
