"the reverb you're looking for"
This review has been selected by our experts as particularly helpful.
As long as it keeps on going I don't think I'll be looking for a new reverb unit anytime soon outside of rackmounts (T.C.electronics and I heard Yamaha and Alesis make some cool ones).
Sound
Great for atmospheric sounds and for ambient experimentation. I've been looking for a good reverb pedal preferably not so digitally-processed sounding and finally tried the electro harmonix route and was blown away. It's simple the way reverb and distortion is supposed to be from the time they were founded. It doesn't sound cheesy like most reverb pedals but sounds very much like vintage amp reverb and very "analog" if that can even apply here. It gives you that ambient tone and feel familiar to sigur ros, radiohead, or coldplay and b/c of its simplicity, it's ideal for experimenting and finding new sounds.
Features
I love the non-complicating features of this unit. All the features on this unit are easily accessible and applicable. The low learning curve of the pedal helps the features to stand out more in their capability to achieve a more clearly desired effect. It's not like the tubescreamer reissues that have multiple settings when the user is only going to be using one of the settings (t9).
Quality
It's built tough and for wear and tear just like the rest of the products in the electro harmonix family. I don't think one would have to worry about anything going wrong with the pedal unless you really have try to go out of your way to do so. Furthermore, I don't know what that guy in the other comments was talking about in regards to excessive noise. Then again, I guess in a church (a religious one that is) any noise out of the ordinary might stand out as being too noisy. =) Only joking. Actually half-joking.
Value
For what it does and delivers compared to other reverb pedals, I think it's a great value. You don't need most of the excessive stuff and knobs and junk that come with the other pedals and that's what the consumer usually thinks he's paying more money for.
Manufacturer Support
I haven't had to b/c I haven't had any problems with it so I just gave this a "10" b/c the "n/a" option wasn't available. Why not?
The Wow Factor
It looks cool and clean just like a reverb pedal should eh?

"Not totally bad, but completely useless in my situation."
Sound
Probably the closest I can say in regards to the sound is that the spring reverb sounds nothing like real spring reverb. I bought this unit because I retired my old cheapo Marshall Valvestate amp with the spring reverb and the Holy Grail hasn't been living up to its name. I can say that it pretty much has two settings on spring - "non-existent" and "way too washed up". I was hoping for just a little sound coloring and this hasn't been doing it at all. For the other sounds I can say that the FLverb is actually cool if I already didn't have a Flanger by the same brand, still though it has some interesting sounds. The hall reverbs are so fake that even my old Zoom 505 has better oom and hall sounds on it than this thing. Luckyli it is still under purchase return guarantee so it is going back to the store.
Features
It basically has a selector switch and a dry/wet mix round knob. It would've been cool if it had some more parameters, like a tone control and pre-reverb settings and a small room setting on the switch would've been nice because all the reverbs seemed way too washed up. It could've been in stereo as well because reverb is expected to be 3 dimensional.
Quality
Quality seems sturdy. The only problem I had is when added to the power out of a pedalboard it draws too much power and a nasty hum comes into your channel.
Value
I am not sure how it compares to other stomp box types, but I think for about $100 you can get a multi fx stomp box unit that has better reverb settings than this. Even the Zoom 505 guitar fx processor is worth getting secondhand just for the reverbs.

"Missing one key element"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I bought this to use with an Orange Tiny Terror which doesn't have reverb. I don't plan on needing another reverb pedal for any of my other amps.
Sound
On a clean channel this reverb pedal sounds great. And with analog circuitry the breakup is nice and smooth. The problem that at high gain, the pedal induces a bit of hiss into your signal and is very washy, even at the lowest knob settings. This pedal would have been perfect if it had a decay parameter that you could turn down. I don't like the banging sound it makes after silencing chords at high gain.
Features
The only thing it needed is a decay knob. Otherwise I like the simple controls. It was mighty white of them to include an A/C adapter as well. Boss makes you spend $20.
Ease of Use
It doesn't get easier than a three way selector for the type of reverb you want, and a wet/dry knob.
Quality
Mostly a metal chassis so that's good. A bit on the thin side, but I don't plan to stomp it into the floor.
Value
The pedal was inexpensive, especially with my store discount.
Manufacturer Support
No need.
The Wow Factor
It's just reverb. Kinda like air, it's not a big deal unless you aren't getting any. Probably the most important of the subtle effects, though.

"Does what is says on the box. Perfect for live use."
Guitar reverb or echo is just that. I do not see a need to replace this, unless it breaks! If its reliable, then i would buy another one.
Sound
It produces pure delay for reverb or echo with no additional noise etc. It does what is says on the box without any fuss. What more do you want.
Features
Came with 9v AC adaptor, nothing worse than flat batteries half way through the gig.
Quality
Seems solid, all steel. Too early to comment on reliability.
Value
Beats the pants off other echo pedals for performance at a lower price too.
Manufacturer Support
Bought it from retailer. No interaction with Electro Harmonix.
The Wow Factor
Looks plain and probably old fashioned - only one knob for goodness sake! It does the job, how often should i repeat this?

"Electro harmonix Holy Grail - Reverb"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Sound
This pedal is the closest thing i've ever seen to a reverb unit. all of my amps are reverb free (Fenders bronco and Showman) and this pedal added an incredible debth to their sound. It has 3 setting Hall , spring and Flerb . I use mostly the spring which duplicates a Fender or Peavey spring reverb tank to the letter.
Features
Uses AC not battereis or converters to deal with just plug it in .
Quality
made like all Electro harmonix gear , Like a Tank.
Value
pedal is a real Bargain at the zzounds price.

"tone sucking noise maker"

Sound

"You have chosen...poorly."
I would strongly recommend demoing other reverb units before purchasing this one.
Sound
I used this pedal in multiple different amps and amp head while demoing several other reverb pedals at the local Guitar Center. The effect sounded un-authentic. No matter which setting I set it to, no matter which way I turned the "reverb" knob (??) I still felt as though I had no control over the reverb. This product needs an attack knob, a decay knob, an effect level control, in addition to it's 3 reverb settings.
Ease of Use
It was pretty easy to use, although I wouldn't have minded some more complications in order to get it to sound good. If quality of sound was intended to be sacrificed in order to seem simpler to use, then I guess it was a success.
