Booking a Mod

A 50% down payment will be collected during checkout for booking a modification. The remaining 50%, plus return shipping, will be due when the modification is complete. You will be prompted to choose a mod date when you add a mod to your cart. After booking, you will receive an email confirming your chosen “mod date” and shipping details.

The interface is not included in the mod price. You must supply us with an interface to be modified.

Please read our full sales policies prior to booking a mod.

Mod Rating

We often get asked our opinion on how one interface compares to another, so we’ve decided to create a rating system based on subjective A/B listening tests. The scale is from 1-10, with “1” being unimpressive audio quality and “10” being true audio excellence. This is an exponential scale, so going from “1” to “2” isn’t nearly as big of a jump as going from “9” to “10”.
Please keep in mind, we only modify an interface if we can make a significant improvement to the sound. All of our ratings are ultimately a matter of opinion. To view how we rate all of our mods, click here.
