Electro Harmonix Holy Grail Nano Reverb Reviews

Everything except flerb is good!

This is the first reverb pedal i tried, i think i will be replacing it eventually because i am getting a tonemaster twin, so there will be more spring reverb than you ever need.

The pedal itself is great, the only bad thing about it is the flerb setting, which is trash)

It's just okay...

Doesn't sound one bit like my old Holy Grail. What happened????

Reverb

It does what it has to. Simple and practical. Flerb function is awesome.

it is good but not perfect

i guess the knob doesnt adjust just the effect level but also the decay, therefore you cant have a pronounced reverb sound without having a long, a bit fake and annoying, reverb.

Still it sounds good but not like an amp, i wonder if they changed something from the old nano holy grail

Trusted and great reverb pedal.

I was in search for a simple but powerful reverb pedal to shape my tone. EHX always builds great pedals in my experience that will last a long time. The Spring and Hall reverb really complimented the missing reverb on my Marshall Origin 20H. It delivers great vintage reverb to my ears. The Flerb setting might sounds weird to most people's ears but with some creative tweaking, can deliver unique sounds. Especially when it's paired with other effect pedals that add modulation.

A rival to Spring Reverb if reasonnable

A very good pedal if one remain reasonnable in the settings.

Pushed too far it sound more like a special effecte in spring mode.

This rating is for the older version of the Holy Grail.

Lush spring surf reverb

I really really like the spring reverb and that was the reason i initially bought it. It is very close to Fender-amp reverb that i prefer.Also, I like the simplicity that it has only one knob. The Hall reverb it is also nice till 12oclock setting. Flerb i do not play at all, i would prefer a Room type instead. It does not seem to affect my tone as it is true bypass

Best reverb pedal

Love this pedal!

Bought it because it's used by Tame Impala's Kevin Parker. Not disappointed.

I read in other reviews that people don't really enjoy the Hall mode, but I cannot agree. I mostly play in Hall, and if you use it before compression in bridge pickup, it sounds absolutely psychedelic! I have to agree that it is a bit weird if you turn it past 3 o'clock, but till then you have more than sufficient reverb, besides you can experiment with the obvious delay that appears if you turn the knob over 3 in Hall mode.

The power supply got me confused, initially I thought that this pedal could be only used with that specific adapter, but I'm using it with my HB Power Plant without any problems.

Small, light, many features, great sound, power adapter included - great deal!

Electro Harmonix Holy Grail

EHX Holy Grail is one of the very best reverb pedals in the market.

Pros:

- Has many possibilities of reverb tones (Spring, Hall and Flerb)

- Only has one knob and it's perfectly enough

- Especially the spring reverb has a very nice and warm tone

- It works perfectly from a subtle jazzy reverb to a full wet psychadelic reverb

Cons:

- The flerb sound is a bit strange at first, but after some practice you get more used to it's flangery mood

- Can only be used with the original power supply that comes with the pedal.

Conclusion:

Although the small size and having only one knob this pedal can turn in a verstile tool to you guitar sound.

Put it in the end of your pedal chain, plug in your guitar and discover by yourself the magical world of reverbs.

Great sound

I only use one pedal with my custom made Fender Deluxe 57 amplifier, and it's this one. With my Fender Deluxe Reverb re-issue, I use the reverb from the amplifier itself.

My custom self hand wired Fender Deluxe 57 doesn't have reverb and the Electro Harmonix Nano Holy Grail does a great job!

Nice Pedal

I bought this to replace a very old electro harmonix pedal which had "died". Great little pedal, nothing fancy but does a great job. Much more compact than the old pedal and it looks pretty bombproof so should last for years like the old one did

Sweet. Simple. Reverb.

I bought this pedal based on the fact that it was highly regarded, had good reviews, and that one of my musical heroes uses one. I was not disappointed.

The spring reverb effect was what I was really after, it offered me a very simple reverb sound that went beautifully with my clean tone. Given there is only one parameter knob on the Holy Grail, you can't tweak as much as you may like, but for a rhythm guitarist such as myself this didn't affect me too much.

The 'Flerb' setting is not something I had given a large amount of thought but after a play around with it I've found it to be quite an interesting sound. A nice addition to the pedal whilst again taking into consideration the price and size.

The only real criticism I would have of the Nano Holy Grail is the 'Hall' setting. When it's turned past around 3 o'clock, the delay between playing the chord and it coming out of the amplifier is large and noticeable. I am unsure whether this is a problem many people have as I have not looked into it but I feel it makes the 'Hall' setting relatively unusable.

The EHX Nano Holy Grail 'spring reverb' is definitely something I have kept in my pedal chain, even though I now own a Strymon Big Sky as well.

Great sound, a bit limited

This is a pretty straight forward hall pedal. The spring reverb sounds great, I like it just as much or more than the one in my amp. Until 12'o clock I'd say is the normal range of reverb for me, higher settings are good for an extreme effect. One thing important to know is that with higher settings, all parameters of the hall change, so not just decay and mix, but also predelay. The features on this pedal are a bit limited in that sense, in return you get the very small size.

One thing that is a small problem for me is the loud acoustic click-noise when you turn the pedal on and off. The switch has more resistance than the one on my freeze and is also a lot louder, this is a problem for me because I play a lot of quite music, and initially I wanted two have a little amount of hall set on my amp, and use the holy grail to add more hall. At the moment I try just switching between more and less hall by turning the knob with my foot, which works pretty well, or I will get a new, quieter switch for it someday.

With a quieter switch, this would be the ideal hall pedal for me, because it sounds very good and is so straight forward, you can't loose yourself on the knobs because there is just one ;)

Okay

Simple reverb. Three settings. Spring is quite nice. Hall is a bit too big for my taste. Flerb is pretty useless with a preset flanger on the reverb sound. Great build quality but haven't been blown away by it. Not much warmth, somehow. Will probably look elsewhere for reverb in the future.

Good for its size.

Slimmed down to just about necessities this stomp works good.

Its downside is that it steals a bit of volume som be prepared to compensate.

Otherwise its pretty good reverb (both spring and hall), the flerb is somewhat of a bonus thingie with a very limited use.

Im happy with it.. and its well worth its price.

Electro Harmonix Nano Holy Grail: so-so

This small pedal is catchy as it appears simple to use, with only one know to control to amount of reverb. However, I find that past 11-12 o'clock it sounds far too metallic and treably, almost like a fuzz / distortion effect. It seems to loose control of the signal. For my normal use, I do not go past 9 o'clock. The flange feature is useless to me, and probably to most people, unless one is interested in that particular effect. I prefer the Boss reverb pedal, with separate controls for MIX (dry versus wet signal portions) and DWELL (the actual amount of reverb). Besides, the Boss pedal keeps the original signal tone, without loosing control. One additional negative feature (for me at least): the pedal switch is hard to engage and originates an audible metallic clicking noise. I prefer a smoother switch action. I believe that one should go for either the Boss (a bit more expensive) or for the cheaper Beringher units, that are indeed quite satisfactory sound-wise.

Electro Harmonix nano holy grail,

this is a excellent reverb pedal, I own the original bigger box version and it is great also but is fussy on power supplies and requires at least 500ma, the nano version is small, rugged and sounds the same as the original and will work perfectly from any normal boss style power supply, its spring an hall settings are great sounding and the flerb setting is very cool sounding effect that only this pedal can achieve, if you want a very high quality reverb that's a small footprint and reliable, go for the nano holy grail, I highly recommend it, sounds great on all settings!!!!
