DiMarzio has a great policy where you can play their pickups and, if you are not happy with the sound, you can exchange them within 30 days of purchase for a set of DiMarzio pickups that is a better fit. If the desired pickups are more expensive, you will just have to pay the difference. Full details on the program as well as return instructions can be found here.
This guarantee does not come through GuitarPickups.xyz; please do not send your pickups back to us - please send them to DiMarzio via the instructions above. You will need your original receipt, so if you lost that no worries you could reprint it from our order email or ping us via our contact us form and we'll email it to you.
Note: DiMarzio may choose to change this policy at any time. The above description is a summary of the policy as of the time of this writing (9/29/2015) and does not guarantee the policy will be as described.
