    O.K. I guess I'll be the first to review the Holy Grail Plus since no body chose to do so. This should answer any questions that you might have about the HG+. I own both the HG and HG+ and will give you my honest opinion of both.The HG+ trumps the original Holy Grail. The HG+ has the same lush, natural tone as the HG, but goes a step further. It gives you the ability to control both the amount of reverb(length), and how much of the effect you want mixed with your dry signal. The HG only has one knob to control the level and length of the effect. I run my reverb pedal through the effects loop. I found that I could only use a tiny fraction of the reverb, almost to the point where the effect was practically non existent. Using larger amounts would muddy my tone. Not what I want from a reverb pedal.The HG+ allowed me to increase the amount of reverb to my taste and blend that signal to my dry signal without degrading my tone. It's just what I've been looking for. Now I have that great reverb tone that I got from the HG without it washing out my tone. Another advantage, the HG+ has a lower profile which makes navigating around the pedal board much easier. The casing seems to be more durable as well. If you are looking for an easy to use reverb pedal that is flexible and sounds great, the HG+ is for you.

    This pedal sounded magical when I first purchased it. There are so many ways to tweak the sound of the different types of reverb that it seemed like the skies were the limit. After treating it very gently for a few months, it just stopped working one day. I've asked around and this seems to be a common problem with this pedal. EH doesn't make quality products like they used to. I switched to the T-Rex brand reverb pedal and plan on never purchasing any EH products again.

    Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

    It took me quite awhile (and a lot of research) to decide I needed this pedal. I mean, come on...reverb is the most basic effect and has been standard equipment on just about every amp made in the past 50 years. The reverb in some amps is better than others, but just how good does it have to be?

    If you play pedal steel guitar like I do, it turns out that reverb is an essential part of your tone. Even after upgrading the reverb tank in my steel amp, I wasn't getting that depth of reverb tone that I was looking for....and of course, anybody who has experience with spring reverbs knows that they get very sensitive to movement when you turn them up to the higher settings onstage.

    The Holy Grail Plus solved these problems. It does one thing and does it well. It has a very authentic sounding "Spring" reverb, as well as "Room" and "Hall". For my purposes, the "Flerb" (flanger & reverb)is useless, but that doesn't matter. The important thing is that with the versatility of this unit, I'm able to select the ONE setting that works for me.
    The Holy Grail Plus has 3 knobs, giving you some extra control to fine-tune the effects.

    "Reverb" switches between 4 main types of reverb: Spring, Hall, Room, and Flerb.

    "Amount" controls the intensity of the effect.

    "Blend" mixes the wet and dry signal.

    Initially, I would have preferred a unit that contained both reverb and delay....which is my default guitar setting. In fact, the unit would be more useful if they added delay instead of flange in the "Flerb" setting and called it "Derb" As it turns out, the "Hall" setting does something similar. In simulating the sound of a hall, it mixes the echo from the virtual walls with the "wet" reverb signal. If you turn the "Amount" and "Blend" knobs to full and hit a string, there is a delay before you hear any sound at all. Delay! Setting both controls around 12 oclock gives you a nice blend of delay and reverb.

    I like that this pedal comes with an AC adapter rather than a battery. It's also very quiet. With regards to background noise, I can't hear any hiss or white noise at all.

    The bottom line is that although it seems a bit counter-intuitive to buy an effect that's already built into the amp, the Holy Grail Plus does the job better, and gives you a lot more options and control over your reverb. I'd definitely recommend the Holy Grail Plus to anybody who needs something better than their stock reverb.

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      I bought an EHX Memory Boy and really loved the surfy tremolo-effected delay, but I still felt for something roomier. I love the warmth I get for this pedal for leads and un-distorted chords, but this pedal FATTENS UP all of your tones without making it bassy (as Phasers and Flangers tend to oscillate into a bassy boom sometimes). You will burst when you hear your leads through this!

      I did a lot of research for guitarists whose Reverb tone I liked, and almost all directions pointed to EHX. Mind you, I'm aware that some of these players use digital reverb during recording, but I looked at player's live setups too (and I've seen these guys live.) For example, Foals and Tame Impala (Tame Impala's Kevin Parker incoporates a Nano and regular HG. I chose the Plus because I like options!)

      Don't be afraid to throw the Amount (of Reverb) on full. It will still sound tasteful, but it's up to you and your preferences.

      At 27 years old, playing guitar for 15 years, and playing live shows with bands for 12 years, I really respect and revere the sound that this is capable of. Play with it for a while and then without it, and you'll see. It gives a more mature character to your playing. I fool you not.

      You may think, "wow, over 100 cold ones for a REVERB pedal?" but if you can afford it then you WILL be thankful for what this can do for your tone, ESPECIALLY WHEN YOU PLAY LOUD!
      If you can't afford to buy this pedal new, BUY IT USED! JUST GET ONE.

      The flerb is a really cool effect, but like another user reviewed, I haven't yet thought of a way to use it tastefully. It's a bit wacky, but cool nonetheless!

      Spring gives you that light instant-bounce reverb.

      "Hall" gives you that epic, full, vintagey sound that I (and maybe others?) really characterise as that paradigm Reverb sound.

      "Room" gives you a neater, but still full and cozy, Reverb sound. Really great for the lightly fuzzy, twangy post-punk indie chords (think Bloc Party/ the Hives). At least that's what I've used it for so far.

      I ADORE these different types of Reverb on this pedal. If the Reverb doesn't fit the music you're playing, try another one (of the 4 Reverb types!) and I'm sure you'll find a fit.

      Who knows, maybe you're that lucky dude who can pull off the Flerb!

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      So I was tired of using just my amp reverb. I wanted something extra to help get a super erie sound out of my rig for a couple songs, and i thought this pedal would do the trick. And it absolutely did. Here is the problem though. Stand alone, this reverb is great, but when you add other effects with it, it's a MAJOR tone sucker. I tried putting it in the front of my signal train, in the middle, at the end, nothing helped. I tried turning off my amp reverb to use just this, that didn't help either. Long story short, this pedal is not worth the money unless you really dont care about tone. That's it in a nutshell.

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      So I wanted an easy to use versatile pedal to make me sound like I'm in any sized room I wanted, but I got more. This pedal is so simple, I was using it wrong the entire time (Amount to full, blend to full) but it still sounded sick.
      It's spring reverb gives you an awesome clean bounce while the hall can make you sound like your in anything from a hallway to a cathedral. It also has "Flerb" which is a flanger and reverb mix, which is a strange feature, so far I've only found one place to use it, but it's still a really interesting effect. The only thing I can find that I don't like about this pedal is that it has a bit of white noise that comes out, on or off, especially if the batteries dying, but I don't usually use batteries.

      Lost in Space

      By Luke-rcv9I

      from Toronto Ontario

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      I have an older version of this pedal. Its the version with the single very large amount control. That, the footswitch and reverb switch. Spring, Hall, Flerb.I never believed in reverb, thought that many guitar players lost there tone and edge by adding to much. this ped changed all that. No I am in love with the erie sounds that can be achieved with this ped. the added depth the massive space you can create.the only disadvantage to my version is that I can not blend the dry and wet signal. That would make it perfect.the draw back to this version is that the knobs are to small. With the large one on my version I am able to change the amount of reverb on the fly. awesome for dynamic changes. I picked up mine used, it had some issues, had to be ran on its own plug to work probably. It would not work well on the power plus 2 with my other pedals. Not because the pedal is faulty, it just draws a lot of juice. Give then a try

      Tone Sucker

      By ToughGuy

      from Miami

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      I have no idea how this pedal can get such good reviews. I does have a reletivly good reberb effect BUT beware of the backround sounds when you add some drive to your signal, like a humming, even when the effect is not engaged !!!! Also, I added this to my effect board and all of a sudden ALL my amps sounded crappy...I finally pulled this off my board and everything went back to normal. This is my second attempt at buying/using EH effects....you can keep them!!!!! There will not be a third time...

      A Very Big Plus

      By Squirly D

      from Madison, WI

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      A rig without reverb is pretty sterile and lifeless to me, and this pedal is exceptional and sounds very natural. I went with this model of the Holy Grail because of the blend and amount adjustments. There's so much more control over the output. I use the spring setting pretty much all the time, although the hall is very lush. The flerb is quite weird but interesting, but I don't think there's a real practacle place for me to use it quite yet. There's a lot of fun to be had playing around with just the full wet signal on the hall and flerb settings. It works well and sounds awesome with my #1 Echo in front of it. Seems tough and reliable. It doesn't seem to alter the tone and there's no added noise to speak of. I only knocked it down a point because it's sorta spendy.

      Definite Holy Grail

      By Andydj

      from San Diego, CA

      Comments about Electro-Harmonix XO Holy Grail Plus Variable Reverb Guitar Effects Pedal:

      I already have the Holy Grail, and it's the best reverb I've ever used. The only problem I have with it is that, the similar styled Small Stone, it tends to cut the volume level of your amp. I was building a separate pedalboard for my AC-30, and was looking at different reverbs when I saw this. I basically just use the hall reverb, and for the most part, I tend to leave my control knobs at the halfway point on all of my effect settings. It's nice to have some more variables though. This pedal is built sturdier than it's sibling, and takes a standard 1/4" input jack.
