Congratulations on your purchase of the Holy Grail Plus. The Holy Grail Plus starts with the sounds found in the Holy Grail and Holier Grail: Spring, Hall, Room and Flerb. An AMOUNT knob has been added to give the musician further control over the reverbs.
- EFFECT DESCRIPTIONS -
The Spring Reverb effect is a simulation of the spring reverb found in many classic guitar amps. In SPRING mode, the AMOUNT knob controls the size of the spring reverb. The further you turn the AMOUNT knob clockwise, the bigger the spring reverb will be. Set the AMOUNT knob to 3 o’clock to obtain the Spring Reverb found in the Holy Grail.
Hall Reverb is a simulation of the reverb heard in a large space In HALL mode, the AMOUNT knob controls the reverb time. The further you turn the AMOUNT knob clockwise, the longer the reverb time and the larger the reverb space. Using the AMOUNT control you can obtain reverb spaces from a room to a large hall. To obtain the Hall Reverb sound found in the Holy Grail, turn the AMOUNT knob to 4 o’clock.
Room Reverb is a simulation of the reverb heard in a small space. In ROOM mode, the AMOUNT knob controls the damping factor of the reverb. As the AMOUNT knob is turned clockwise, the reverb will be less damped. Set the AMOUNT knob to its minimum position (full counter-clockwise) and the reverb will be heavily damped, sounding like a bathtub reverb. Turn the AMOUNT knob to full clockwise and the reverb sounds like an open room with no damping.
The Flerb Reverb effect is made up of a reverb followed in series by a flanger. In FLERB mode, the AMOUNT knob controls the rate of the Flerb’s modulation. As you turn AMOUNT clockwise, the rate of modulation increases. To obtain the Flerb sound found in the Holy Grail, turn the AMOUNT knob to 8 o’clock.
