I just got the Helix LT. I'm running this through a Marshall 2061x "Handwired" and matching 2x12 cab. this is a simple plexi amp with no bells or whistles just great tone. The problem is I want to hide the amp's characteristics so that I can use Helix's amp models and have them sound like they're intended to. Fender, Vox, etc. What do I need to do to hide the natural Marshall tone so the effects tone can shine through?
