Feature:
Straight up, no BS. A pedal and a pot. The pot may or may not be used, depending on the application. The pot is mounted so that the top is flush with the side of the pedal which keeps it from being broken or accidentally turned.

Quality:
Even though it's a light plastic pedal, this thing can take some serious abuse. My only beef is that the cord is attached to the pedal. Some people might consider this a feature, but I prefer to be able to disconnect the cable.

Value:
This is hard to rate. The pedal does what it's made to do and does it well. That being said, I think it costs a little too much for a plastic unit.

Desirability:
Having tried a bunch of different expression pedals, I always come back to the EV-5. It's so good, I'm getting another.

Sound:
This pedal does not produce a sound, but it helps you to control devices that do make sounds, and in that capacity, it is very good. I have owned a used EV-5 for over six years and have used it live and in the studio extensively, with a number of devices from rackmounted multi-fx units to stompboxes. I am currently using it to control the low pass filter on an xotic Robotalk pedal. The EV-5 is deceptively sturdy, has a decent feel to it, and always functions flawlessly for me. I have tried other expression pedals (Don't use this for volume), including the much more expensive Roland EV7, and they just don't cut the mustard.

Ease of Use:
Very easy to use. Plug and play.

Overall:
If someone comes up with the guts of the EV5 in a metal housing (like an Ernie Ball volume pedal) and a jack instead of a fixed cable, I'll replace my EV5 in my setup.

This is a great pedal for me and my organ sounds and the expression required for gradually engaging the overdrive.
The pedal tracks smoothly and the adjustable volume throw-width/depth is a welcome feature every now and then.

Feature:
The minimum volume switch works just fine. No other features available

Quality:
It's cheap lightweight plastic. You better treat it gently. No functional problems yet.

Value:
Well, it don't cost much and that's what you get. Still too expensive, if you ask me.

Desirability:
I can live with it, even did live gigs with it, but it wasn't a pleasure.

Sound:
It doesn't cut off the sound smoothly at the low end. At minimal volumes the sound tends to get "brittle".

Ease of Use:
Pedal travel is much too short for volume control. I opened it to see what I could do to remedy this. But the problem is in the design and unless you are an experienced home constructor there's no chance you can alter the mechanic towards longer pedal travel. What really bugs me: THERE IS NO WAY THEY DIDN'T NOTICE THIS WHEN THEY CONSTRUCTED IT.

Support:
No need for support yet.

Overall:
I wish there was an alternative to the grossly overpriced EV-7 but it seems there is none. F...

The summary says it all. I have used this as a volume controller for a Viscount D9e organ module and as a controller for various functions of a Roland RS-5 synthesizer. The angle of travel of the pedal is too limited for me. It feels awkward to use it.
