What Electro Harmonix say.....
Every musician battles hum in their signal chain. The Hum Debugger turns it into dead silence, courtesy of a little EHX magic. Not a noise gate, and not a noise suppressor -- but a real hum extractor. Silence is golden.
-CONTROLS and I/O Jacks-
NORMAL/STRONG TOGGLE SWITCH - Sets the amount of Hum Elimination. In NORMAL mode the Hum Debugger removes only the odd harmonics from the hum present in your signal. In STRONG mode the Hum Debugger removes both odd and even harmonics from your signal’s hum content.
STATUS LED - When the LED is lit the Hum Debugger is active. When the LED is off the Hum Debugger is in True Bypass mode.
FOOTSWITCH - Toggles the Hum Debugger between active and True Bypass modes.
CONNECTIONS - Connect your instrument to the INPUT Jack. Connect your amplifier or the rest of your effects chain to the AMP Jack.
POWER - Plug the barrel connector from the AC Adapter that came with your Hum Debugger into the power jack at the top of the Hum Debugger. Plug the AC Adapter into a solid wall outlet. You must use the AC Adapter that the Hum Debugger came with and the AC Adapter must have an output of 7.5VAC with the ability to supply at least 200mA of current.
-Using the Hum Debugger-
There are no special tricks necessary when using the Electro-Harmonix Hum Debugger. You can use it like you would any other effects pedal. The only thing to remember is you must use the AC Adapter that the Hum Debugger comes supplied with.
When using the Hum Debugger first set the toggle switch to NORMAL mode. NORMAL mode should work well in most situations. If you find that the Hum Debugger is still letting some hum through then move the switch up to STRONG mode, this should remove the rest of the hum.
If you use more effects pedals than just the Hum Debugger we advise that the Hum Debugger be inserted at the beginning of the effects chain.
WARNING: Use only the 7.5VAC/400mA AC adapter the Hum Debugger comes supplied with. Do not use any other AC adapters. Using other AC adapters, even those made by Electro-Harmonix, could cause harm to the unit, the adapter or your drummer. The Hum Debugger does not use batteries.

Our chosen couriers are currently operating as normal and all orders should be delivered on time. DPD are also now operating a "contact-free" service as a standard process and customers will not be asked to sign handheld units.
Order before 2pm, Monday to Friday, for same-day dispatch of in-stock orders. Very heavy items such as pianos may take longer to deliver. In-stock orders placed over the weekend will be dispatched on Monday. Estimated delivery times for out of stock items are to be used as a guide only, these items may take longer than estimated to arrive. While we try our best to ensure rapid delivery of your order, delays may occur which are outside our control, and delivery of large or bulky items, or to remote or non-mainland addresses may take longer than estimated.
Most UK deliveries are shipped by our trusted courier, DPD. You'll receive an email with a delivery day, tracking and a one hour estimated delivery window on the morning of delivery. While we can't specify the time of the delivery, if it's not convenient, you can arrange directly with DPD for an alternative delivery date or request the parcel be left with a neighbour.
For heavier items, we usually ship UK deliveries by TNT. You will receive an email with tracking details when we ship your order.
Delivery to mainland UK addresses is free on all orders over £99. Delivery charges are based on the size and weight of your order and, in some cases, your location. A standard next working day carriage charge for UK mainland addresses is shown on the shopping basket page, but you can change delivery service later in the checkout.
We use a few different delivery couriers, depending on the items being sent, your location, and the delivery service you've chosen:
Most orders will need to be signed for and we advise you make sure to check your parcel/s for any damage before signing. If no-one is available at your address, a card will be left so you can arrange a re-delivery directly with the courier. Redirection of an order after it's been dispatched may incur an extra charge from the courier.
Delivery charges displayed apply to most UK mainland addresses. Deliveries to Northern Ireland, UK non-mainland, and European addresses will cost more, and carriage charges will be shown at the checkout before you place your order. Free delivery offers may not apply to some remote/Scottish Highlands addresses.
There are currently delays for all returns processing due to extra safety procedures. Thanks for your patience during this difficult time.
