Product introduction
Comment And Reviews
This is an extremely good volume pedal. I have not had a lot of experience with volume pedals, but I will try to break down each set of criteria in order to convey the quality of the product.

CONSTRUCTION: Very well built, very solid pedal. It is huge though, bigger than my full tone wah pedal in every dimension. The part that moves the pot inside is also a metal blade, unlike other pedals that use either a rubber band or string to apply tension to the interior pot.

TONE: There is very minimal tone loss. With the volume pedal, my signal is going through the volume pedal and a couple true bypass pedals (compressor, wah, and OD) When I hooked my guitar up directly to the amp, there was very minimal high end reduction. It basically sounds like you added a tone knob and turned it down to 8-9 instead of 10. Now, this could be the pedal, or it could also be the lengths of cable going into the pedal and then into the amp being shortened by half when I disconnect the pedals. That’s being said however.... It was not enough loss to have me change any of my settings besides maybe my tone knob on the guitar I cranked up a tiny bit. In other words... if you are a tone hound and small things will drive you nuts, maybe a volume pedal isn’t for you (inherent in the design of a volume pedal there will almost always be tone loss as a volume pedal IS a potentiometer which has resistance, no matter what you do).

Others have commented that there is a cliff, this is true. BUT something to keep in mind about potentiometers again.... they usually work as AUDIO tapers, what this means, is that it tapers your signal on a LOGARITHMIC scale, not a linear scale. Using a logarithmic scale, a volume pot at roughly volume 5 wont be giving you 50% volume, but instead will give you 10% (logarithmic scaling is NOT 1:1). So again, inherent in the design of something that has an audio taper, is that is operates on a logarithmic scale, which means, that as you keep decreasing the volume, the effect becomes more drastic as you roll more off..... I.E once the volume starts dropping... it REALLY starts dropping.

even with some minor problems, this pedal is very handy. I play a lot of musicals and frequently I am being used as a percussionist, which in todays world means using a great deal of electronics. A volume pedals lets me adjust my electronic signal without having to drop to the floor to hit the mixer knob when a sound is too loud or too quiet. This pedal is also handy on the guitar, and even if you never wanted volume, it can be used as an expression pedal for another effect of some type. Overall, this is a very versatile piece of equipment and can be JUST the thing you need if you find yourself having to adjust volumes of electronic equipment on the fly and need an easy way to swell, diminish, or just adjust the output level.
Like everyone else has stated it’s huge but it’s also surprisingly light weight. Because it’s so big it feels good under your foot. The resistance (which is adjustable) is, to me, just right because instead of fighting against you, it’s follows you like a shadow. And as others have mentioned the taper is pretty steep. Once you get the pedal to about 40% open, you’ve got 90% volume. That’s not necessarily a bad thing, it’s just something to get used to. What would be great is if you could adjust the taper of the volume. Maybe there’s a mod floating around on the interwebs? You can set the minimum volume which could be useful for using it as a boost right before an overdrive pedal whereby you set the minimum volume and put the pedal all the way down and when you want to melt some faces, you can open up the pedal all the way to slam the overdrive into...overdrive. I put the volume pedal after distortion and before modulation. That way I can swell into the modulation, delay, and reverb while preserving the trails of the effects that come after the volume once the volume is all the way down. My biggest gripe would be that the jacks are recessed into the enclosure. You can use a 90 degree connector for the top of the pedal, but it’s a juggling act. The side jack for the tuner can only be used with a straight connector. As it would happen, because the pedal is so big, it takes its own entire section of my pedalboard, so space at the top of the pedal wasn’t an issue. I did opt to use straight jack connectors from the top because I had the space and I didn’t want to stress the connectors on a 90 degree jack. Overall it’s a good volume pedal. I dinged it one star because of the volume tapering and recessed jacks. I still think it’s a better volume pedal than the others in its price range, but there are better volume pedals out there.
Update: I added a photo of the FV-500H next to a Boss FV-30H for size reference.
I bought this after returning a Boss FV-50H as it was made of plastic and wouldn’t have the durability I need. I am so glad I did.

This is true Boss/Roland quality. Solid metal casing with a larger volume sweep than the FV-50H. Heavy and with rubber feet so it won’t move. Big enough for big feet and a truly non-slip top. There are also heel and toe bumps which sets this pedal apart, even from more expensive ones like Morley’s Little Alligator. This allows me to know exactly where my foot is on the pedal so I can be sure of the same foot position at all times. This makes use more consistent and predictable.

In addition, there is adjustable baseline volume and adjustable tension to give the pedal more resistance if desired. Dedicated tuner out with no impact on output volume or increased noise. It even can double as an expression pedal.

Only potential issue for some people might be the weight it adds to a pedalboard - 1.6kg.

This is the best volume pedal I’ve used and I expect it might be the only one I will ever need.
Used for several months now and getting used to it. Works reliably and well made and strong. Feels like a quality build as expectedfrom Boss, not a lightweight object and hence the cost. I like the side connection for a tuner and the ability to adjust the minimum volume. Only issue I have had is that the volume change does seem very sensitive at the lowest levels so make nailing the first note level a bit difficult but I suspect that is my skill level and will become easier with more practice.
Really enjoying using it.
Be sure to check which version you need, this one is direct from the bass guitar and for me, goes directly into the amp.
There’s sturdy, and then there’s this pedal. You really wouldn’t want to drop it on your foot because it’s very substantial indeed - and you need that in a volume pedal. My last Boss volume pedal withstood heavy use for over thirty years and it’s still in service, although it does need regular cleaning to stop it getting noisy. This one is even more robust, and noise-free. I suspect that this one will last longer than I will...
Simply does the job it was made for.
Good size, it’s actually a really big pedal but, you need it.
Great for all volume control, you can be a subtle as you like.
Volume pedals aren’t the most exciting items on a guitarist’s pedalboard, but a very valuable tool for adding ambient swells and boosting volume for solos. The Boss FV-500H High impedance volume pedal does all this and more perfectly and is built like a tank so I expect it to last for years with normal use. It can also be used as an expression pedal, although I haven’t tried this function yet.
