Hi. How Can We Help?

Whether you need to locate information for your EHX product or have questions regarding an online order with EHX, we are here to help.

Shipping & Delivery

Electro-Harmonix partners with Quivers for order fulfillment to help support local music stores and our extensive network of authorized dealers. Your order may be shipped or partially shipped from a music store close to you. This greatly reduces shipping time and helps get the product you want in your hands sooner.

Once your order has shipped, you will receive a confirmation email from Quivers. Occasionally, even after an order has been placed, products will be oversold. If this happens, you will be notified within 48 hours that part of, or all, of your order cannot be fulfilled and has been cancelled. Thanks for buying Electro-Harmonix!

Order Processing

  • Standard processing time once an order is placed is 2-3 business days.
  • Unless specified otherwise, all orders are shipped using FedEx ground service and typically takes 3-7 business days.
  • Estimated arrival dates are not guaranteed. Weather delays and other circumstances may impact delivery.
  • Electro-Harmonix is unable to ship to PO Boxes.
  • Electro-Harmonix is not responsible for lost or stolen packages which are confirmed to be delivered to the shipping address provided during order checkout. Upon inquiry, EHX will confirm delivery to the provided address, date of delivery, tracking information and shipping carrier information for the customer to investigate.

If you have not received your delivery after 10 business days, please contact Customer Support and we can help you check on your order.

Cancelled Orders

Electro-Harmonix and our dealer network jointly make every effort to keep items in stock. Occasionally, even after an order has been placed, products will be oversold. If this happens, you will be notified within 48 hours that part, or all, of your order cannot be fulfilled and has been cancelled. We apologize for this inconvenience. Since your card is not charged until your product has shipped, you will not be charged for your order and the authorization will drop according to your bank (2-3 business days but contact your bank for more information).

If only part of your order is unavailable, the remaining items will be shipped to you. Your account will only be charged for the shipped items.
