User Manual

OVERDRIVE Footswitch and LED – The OVERDRIVE footswitch selects whether the

Soul Food section is engaged or in bypass mode. When the Soul Food is engaged, its

corresponding LED is lit. An internal Bypass Mode switch is included to select between True

Bypass and Buffered Bypass. See below for more information on the internal switch.

HOLY GRAIL MAX CONTROLS

REVERB Switch Knob – This rotary switch chooses the reverb mode. Clockwise, the

modes are SPRING, HALL, PLATE and REVERSE.

TIME Knob – Adjusts the decay time, or reverb length/size, for the SPRING, HALL and

PLATE reverbs. In REVERSE mode, the TIME knob sets the length of time between striking

a note and the reverb fade-in. While in PLATE mode, when TIME is set to its maximum

position, the reverb decay is over 30 seconds creating a lush reverb wash with each new

note.

BLEND Knob – Controls the wet/dry mix from 100% Dry (counter-clockwise position) to

100% Wet (clockwise position). As the BLEND knob is turned, the overall output volume

remains nearly constant. Your Dry signal remains analog from input to output through the

Holy Grail Max section of the Turnip Greens.

REVERB Footswitch and LED – The REVERB footswitch selects whether the Holy Grail

Max is engaged or in True Bypass mode. When the effect is engaged, its corresponding

LED is lit.

EFFECT ORDER Switch – This toggle switch, located in the middle of the Turnip Greens,

selects which effect is first in the signal chain. With the switch to the right, the signal chain

is OD  Reverb, which produces a sound most players are used to – their boosted tone

with some added reverb. With the switch to the left, the signal chain is Reverb  OD,

which produces a slightly different and interesting sound. Now the reverb is being boosted

by the overdrive which, when used in conjunction with pedals in the effects loop, can

create some very lush textures.

INPUT Jack – This ¼” jack is the audio input for the Turnip Greens. The input impedance

is 1M.

OUTPUT Jack – This ¼” jack is the audio output from the Turnip Greens. The output

impedance ranges from 500 to 3.3k.

SEND Jack – This ¼” jack can be used to put effects in the signal path between the Soul

Food and Holy Grail Max to expand its sonic capabilities. This output can also be used to

split your signal to a separate effects chain or amplifier input.

RETURN Jack – This ¼” jack must be used in conjunction with the SEND jack. Connect

this jack to the output of the effect(s) in the loop.

Internal Bypass Mode Switch – If you remove the Turnip Greens’ bottom cover, you

will see a small switch on the board that holds the footswitch for the Soul Food. It is

located in the bottom-left area of the pedal, below the INPUT jack. Above the switch is the

label TRUE BYPASS and below the switch is the label BUFFERED.

When the switch is set to TRUE BYPASS, its upper position, bypass for the Soul Food

section will be True Bypass. When the switch is set to BUFFERED, its lower position, bypass
