## Description

Review: Whether you want to create sweet deep cave-like reverbian lanscapes or just add that pro touch to a drab amp sound, this EHX pedal has got the lot - and then some - with the added reverse reverb switch. Trip out to the soundscapes and slap yourself on the back as the notes come right back atcha - before you have finished playing them! In short, this Holy Grail Max pedal works to the max. Buy it now.
Review: Cercavo un riverbero semplice, senza troppi fronzoli e senza programmazioni complesse che facesse quello che un riverbero deve fare in modo intuitivo ed immediato. Collegato alla pedaliera la soddisfazione è stata immediata. Le tipologie di riverbero offerte sono 4 e tutte eccellenti ma Il riverbero per quanto mi riguarda è HALL. Lo SPRING è fantastico per suonare surf rock oppure rockabilly e va alla grande. Il REVERSE è molto interessane per creare effetti particolari.

*by G***N on 6 February 2016*

Absolutely perfect! What else can I say. It does exactly what it's supposed to do, and sounds fantastic. I play in a Beatles tribute band so there are definitely times where I need some added reverb outside of my amp's internal reverb. I put the Holy Grail Max at the end of my effects pedal board chain and it sounds amazing. The whole band thinks so. Since I'm mostly playing early 60's music, I've got it set to the spring reverb setting which sounds incredible. Very, very, similar to the reverb in my Deluxe Reverb tube amp. The plate reverb setting is also amazing. Tough to decide between those 2 settings. Going with the spring reverb setting for now. One thing to note, unlike some other guitar effects pedals, when you step on this pedal, you will NOT notice a drop in volume. It just adds a beautiful layer of reverb into your tone. Love this pedal. This is my first Electro-Harmonix pedal, and I'm very impressed. I've been using fx pedals for about 40 years, and this one is a winner!
