EHX HOLY GRAIL REVERB DUAL MOD

KINNATONE ELECTRO HARMONIX HOLY GRAIL DUALLY MOD ( EXTRA PRESET)
Ever think It would be cool to have an extra setting on your Holy grail pedal ? This mod adds another switch to your EHX Holy GRAIL NANO or Holy Grail and another knobs you can switch between to give you another reverb level on this unit.
I can do both versions of this pedal the large box or the nano same price either way.
