Musicians Friend typically allows you to cancel or change your order, but the options available depend on the status of your order. If your order has not yet been processed, you may have the opportunity to cancel or modify it easily. However, once the order has entered the shipping process, it may no longer be possible to change details or cancel it. It is advisable to act quickly if you wish to make changes. To explore the specific details of your order and find out about cancellation or modification, checking the order status on the current web page can provide the most accurate and up-to-date information. There, you may also find relevant contact information if further assistance is needed.
