Purpose and Compatibility

This ABLEGRID 9V AC-DC adapter is built for the Electro-Harmonix Holy Grail Max Reverb pedal. It accepts worldwide AC input from 100 to 240 V at 50 or 60 Hz and delivers DC power through a barrel tip connector. The unit is a non-OEM replacement verified for 101% compatibility with the original power supply. Musicians needing a reliable mains PSU for this specific pedal are the intended users.

Thermals Noise and Protection

The adapter includes over-voltage protection and over-heat protection to guard the pedal and the charger itself during extended sessions. No fan is present, so operation is silent. The supplier notes that the unit should be kept in a suitably ventilated area with controlled humidity if used for long periods, and it should not be placed on skin-contact surfaces. These measures manage heat without active cooling.

Included Accessories and Certifications

The package contains one new AC-DC adapter power charger. The product carries CE, FCC and RoHS certifications, confirming compliance with safety and environmental standards. No additional cables, mounting hardware or software are bundled. The documentation advises verifying the DC output and tip size before ordering and to stop use immediately if any abnormal condition occurs.

Questions about this item

How do I connect the barrel tip to the Holy Grail Max Reverb, and what polarity mistake should I avoid?

Match the DC output and barrel tip size to the pedal before plugging in; the adapter supplies centre-positive DC from a 100-240 V AC source at 50-60 Hz.

What upkeep does the adapter need after months of daily use?

Keep the unit in a ventilated, low-humidity spot and do not rest it on soft surfaces; stop use immediately if the housing becomes unusually hot or emits any smell.

Which protection circuit activates first during a long rehearsal at full volume?

Over-heat protection will trip before over-voltage protection if the charger runs continuously in a poorly ventilated space.
