Electro-Harmonix Holy Grail Max Reverb Pedal Review – 2017

I’m always on the look-out for quality reverb pedals that won’t break the bank. When I was looking for a new pedal, I decided to stick with a company I trusted. Electro-Harmonix has never let me down with their products, which is why I’m here to tell you about the Electro-Harmonix Holy Grail Max Reverb pedal.

Things to Consider Before Buying a Reverb Pedal

Depending on the type of music you play, choosing the right reverb pedal will be a unique process. The Holy Grail reverb pedal will solve the age-old problem of not being able to fine-tune your sound enough with a reverb pedal. However, despite its impressiveness, be sure to consider the following before buying this model:

  • Your genre
  • How complex the pedal should be

Reverb pedals are great for a lot of genres, but musicians who play heavy rock music may want to consider buying distortion pedals first.

Reverb pedals are also quite similar to delay pedals, but they focus more on the setting rather than the echo quality. If you want to learn more about delay pedals, take a look at this article.

The Holy Grail Reverb Pedal Review

Before we get into the Electro Harmonix Holy Grail review, it’s important to know what reverb pedals will do to your sound. Reverb pedals mimic different acoustic settings by affecting the reverberance of a sound. Typically, reverb pedals will have different acoustic space settings, such as “Room”, “Cathedral”, and “Hall”.

One of the best ways to use a reverb pedal is at the end of a pedal chain, which you can learn more about here.

In comparison to the TC Electronic Hall of Fame, which is the leading reverb pedal, this pedal will have fewer settings and may be better for beginners.


  • Easy to use
  • Reliable brand
  • Excellent sound quality


  • Not a lot of features
  • Upper price range
  • No Flerb setting


This pedal has a retro-looking appearance and is really durable, making it a great fit for musicians who move their gear around a lot. The pedal also has three knobs, one of which will allow you to choose from four different reverb settings.

The other two knobs can be used to fine-tune your sound. This pedal is pretty large in size, which means you won’t have any trouble pressing the footswitch. On the other hand, you might want to consider a lighter, smaller pedal if you have a full pedalboard.

1. Reverb

You’ll probably want to start off by selecting a setting with the reverb knob. The setting you choose using this knob will act as your foundation, which you can then fine-tune using the other two knobs.





2. Blend

The blend knob will allow you to control how wet or how dry your sound is. If you’re new to the world of effect pedals, a dry signal is an unaffected sound, and a wet sound is one that has been changed by the pedal in some way.

When musicians say their sound is 100% wet, they mean the settings are turned up to the highest degree. If you like your sound to be as natural as possible, you’ll probably want to leave your blend setting down pretty low.

3. Time

This knob will allow you to adjust your decay time. If you want a more reverberant sound, you should choose a long decay time. This will create a long echo effect that will make you feel like you’re standing in a cave-like setting.

On the other hand, choosing a short decay time will cause the echo to end very quickly, which will create the impression of being in a non-reverberant space, such as a room with concrete walls.


After scouring the internet to find out what other musicians think of this pedal, I’m confident you won’t have any regrets if you decide to purchase this pedal. Let’s take a look at what some other musicians are saying about the Holy Grail Max model:

1. TC Electronic Hall of Fame

This is the other leading reverb pedal on the market, and it’s appreciated by musicians for its number of features that will allow you to fine tune your sound.
