Wanted to reach out and see if anyone else is using the Helix with one or more DT25's or DT50's. I haven't had a lot of luck with this configuration (2XDT25s). Lots of issues with hissing, I can't get the overdrives to sound like anything but fuzzy. The DT25 manual settings don't transfer to the amp model settings (Gain, Presence, etc.). The amp doesn't seem to react the way it does with the HD500 where you can hear the changes in the amp's configuration. There's not a lot in the Helix manual on this configuration where as the HD series has a manual just for the use with DT amps.
