FV-500-H : Robust and reliable workhorse

As robust as such device can be, it works perfectly both as a volume pedal or expression pedal when you connect it to any effect which supports EP.

Movement stays smooth but definite enough.

You can connect tuner separately and this is the feature I actually found quite awesome one the times when I was still learning notes of fretboard. You can leave tuner on as you are playing and you will see the note that actually sounds. It is awesome when practicing bending too!

Another useful feature is minimal sound level. It allows you to set how low volume goes where pedal is at zero position.

Quality is unmached and I would guess you can drive a car over this device.

Price to quality gets very good too.
