Heavenly reverb!

The Holy Grail Nano is a digital reverb in a compact guitar pedal. Holy Grail Nano contains three different reverb algorithms: Spring, Hall and Flerb. All three algorithms were designed and tailored for the electric guitar but they will work equally as well on most instruments and voices. The Spring algorithm is a re-creation of the classic spring reverbs that are found in many guitar amplifiers. The Hall algorithm is a new, lush reverb. Flerb is a beautiful reverb like nothing you have heard before. Holy Grail Nano will change the way you look at reverb!

Electro-Harmonix Holy Grail Nano Reverb Features:
  • Three different reverb algorithms: Spring, Hall, and Flerb
  • Great for guitar, voice, and most any instrument
  • Digital reverb in a compact pedal

"Holy Grail , Batman !"

This unit easily makes your guitar sound like you are in the "BatCave" or just the "BatRoom". Its perfect to add just a touch of Reverb to my jazz rig or full tilt Electro-Pop ! It has a BaJillion settings, thats right, a BaJillion. With its Spring, Hall and Flerb and the Reverb depth dial.. Its soft or hard in your grannies "Ear Candy" dish. I use it with a Washburn Jazz Box and a Fender 1/15 Bass Amp. Love it !

Great pedal, right price

Just got this today and I have to say I'm very surprised. This pedal is more bang for the buck than I ever expected. It's built like a tank, and has a beautiful sound. The Flerb setting is a bit interesting but it's fun to play with. It doesn't have a battery but to me that's okay. The batteries always seem to die quick in my pedals when I don't use the AC adapter. I am afraid I'm going to accidentally hit the little mode switch with my foot and break it off, so you just have to be careful of that. Otherwise, this is a great pedal at a great price.

Holy Grail Nano is simple and effective

The Electro-Harmonix Holy Grail Nano is a digital reverb that is simple, effective and very versatile. There are basically three reverb choices--spring, hall and their own creation called flerb. The spring and hall are pretty traditional and very natural sounding. The flerb feature is unique in that it blends a flanging effect with reverb for some cool ethereal, atmospheric and nice complements, particularly when in the clean channel. Each type of reverb can be dialed in manually on the spot and there are wide parameters to choose from when increasing or decreasing effects levels. Also, it's very quiet and constructed really well.

Excellent reverb pedal

Exactly as described. Easy to use, excellent reverb quality, sturdily built.

Another Great E-H Pedal

Haven't had to use a reverb pedal in 15 years due to having spring verbs in my amps. Gotta new small amp w/o verb so I got a Holy Grail pedal. The spring setting works great between 8:00 and 11:00 on the reverb knob for old rock, blues and country -- 12:00 and above and you're in surf city. Haven't really used the hall setting but it sounds clean and open -- probably good for slow sustained leads. Tried the flerb setting on 2 slow tunes using a Tele & Jazzmaster (both p/u's on each) and it enhanced the sound. Looking forward to exploring that further. A well made pedal that more than met my expectations.
