WOW! Looked into the standard Holy Grail, and for the tiny amount more you pay for the Holy Grail +, I have to say I am very glad I paid the extra cash. The reverbs are lovely, and like all EH pedals I have tested it lets you go from subtle to insane. The extra control over the Flerb makes it a much more usable effect and you can get some fantastic sounds out of it. I can’t recommend this little box highly enough. If you are thinking of getting a Holy Grail, test this baby out as well. Well worth the money.
