The Feedback Resonator is an upgrade to your Sonic Resonator, it fires a projectile that destroys armored bloom cankers, which is a vital tool to clear the Angel Comb and progress through Karakorum. To unlock it you must scan 2 fragments, one found in the wrecks near the power plant while the second fragment is found in the metal farms. This guide walks you through where to find the fragments and how to craft the resonator so you can clear the Angel Comb.
Obtaining Feedback Resonator Blueprint
To get the Feedback Resonator blueprint, you need to scan 2 fragments.
1st Fragment Location
From Alien Base, head east while staying at ~200m depth. Look for the following wreck site as shown in the above image then head inside the wreck through the door.
You’ll find the first fragment to your left after you get inside the wreck. Scan the fragment using the scanner.
2nd Fragment Location
To get the 2nd fragment, head northeast from the Angel Comb and follow its roots until you reach a green glowing area, Metal Farms.
Then look for the highlighted spot near the green glowing pool as shown in the above image and you’ll find the second fragment that you can scan to unlock the blueprint.
Crafting Feedback Resonator
You can only craft the Feedback Resonator through the Modification Station under tool upgrades. You need 4 resources to craft it – sonic resonator, enameled glass, conduit crystal and strontium.
