So I couldn't get my helix to work with the midi controller I bought so for now I've been using my Triple Rectifier as a power amp.... putting helix lt into return in fx loop both dials for loop at 50 percent. Then I use Helix LT Preamps. I gotta say it sounds amazing this way. I set up 3 patches, a lead, rhythm, and a clean. All based off my current gear. The clean using jc120 preamp with 70s chorus sounds just like my jc120 combo. Then the 2 dirty I actually used ANGL preamp for sounds amazing. My question is does the Triple Rectifier as power amp add some tube sound to it? It seems to be very rich sounding and feels a lot like playing my tube amp. Any thoughts or suggestions? Thanks guys.
