Look up onWORKING CONDITION: Excellent. All modes and the gate function work flawlessly.PHYSICAL CONDITION: Very Good. The chassis, knobs, and jacks are all in excellent condition. However, there is a ring of oxidation around the perimeter of the bottom panel. Looking inside the pedal, the internal housing and electronics are all still very clean. See pics INVENTORY #58789 BRAND: Electro-Harmonix MODEL: Holier Grail Reverb FUNCTION: Guitar Effects Pedal PRODUCT DESCRIPTION: This listing is for an Electro-Harmonix EHX Holier Grail Reverb Effects Pedal. The Electro-Harmonix Holier Grail is a discontinued digital reverb pedal that expanded the capabilities of the original Holy Grail by adding more presets and a specialized gate function. Released in the late 1990s and discontinued around 2010, it is known for its larger trapezoidal "oilpan" enclosure and unique "Flerb" (flanging + reverb) effect. SPECS: The pedal features 8 high-quality reverb presets categorized into four types, each with a Long and Short decay setting. Spring: A re-creation of classic amplifier spring reverb tanks. Hall: Simulates large acoustic spaces with lush, tailoring for guitar. Room: Offers damped "room" sounds, often described as a "bathtub" reverb effect. Flerb: A unique combination of flanging and spatial reverb. Gate Function: Includes a post-reverb gate with an adjustable threshold, allowing users to end reverb tails abruptly or use a reverse gate for unnatural, experimental sounds. Power: Requires an 18V DC-500mA power supply (included with purchase). Bypass: Features true bypass circuitry to ensure no digital noise or tone coloration when the effect is off. Controls: Includes a "Type" switch, "Length" (Long/Short) switch, a "Blend" knob for wet/dry mix, and gate threshold controls. ACCESSORIES INCLUDED: This item comes as seen in photos and includes its original EHX power supply adapter. UNPACKAGED WEIGHT: 3 lbs. UNPACKAGED DIMENSIONS: 8" x 4" x 7"
