ABLEGRID 9V AC-DC Adapter for Electro-Harmonix Riddle Q Balls Envelope Filter Charger

Power adapter for Electro-Harmonix Riddle Q Balls

This AC-DC adapter is built for the Electro-Harmonix Riddle Q Balls envelope filter pedal. It delivers a regulated 9 V DC output from a 100-240 V AC mains supply. The unit includes over-voltage and over-heat protection and carries CE, FCC and RoHS certifications. It is a non-OEM replacement that matches the original specification.

Check your pedal before ordering

Verify that the pedal requires a 9 V DC supply with a barrel-type tip connector. Confirm the centre-pin polarity and tip dimensions match the adapter output. The adapter accepts 50-60 Hz mains frequency for worldwide use. Do not proceed if the pedal specifies a different voltage, current or connector type.

Fits a standard pedalboard power chain

The compact wall-wart plugs directly into a mains socket or power strip, freeing a pedalboard DC jack for other effects. No battery compartment or external power brick is required. Keep the adapter in a ventilated area during extended use and avoid placing it on heat-sensitive surfaces. The package contains only the adapter unit.
