Helix/DT amp integration on the way! in DT50 / DT25 Posted January 26, 2019 If anyone has been checking out the information coming out of NAAM, Line 6 has announced that (finally!) with the release of Helix Core, DT amps will be fully integrated through the Line 6 Link connection. It will connect fully just like the HD series does, so you can control topology, class a/ab, triode pentode and preamp model. An added bonus is that you will be able to control all these parameters via Snapshot on the Helix. So cool!
