Well I won’t give out any guess work for any Line 6 user, so here is your answer. Simply hold down simultaneously foot switches 7 & 8 respectively and Helix on. You will then let go of foot switches 7 & 8, then you will see the Line 6 Helix Logo appear with a message under your Helix (s) firmware informing you “ We Will Rebuild Your Presets” and you’re good to go , however, please note that this type of Helix reset will not overwrite any and all of your own creative presets. So, with this in mind, you can reset the Helix to factory presets without overwriting/destructive, your own creative presets.
Many Blessings
