wvheld Posted January 13, 2019 Share Posted January 13, 2019 At wits end. I have the Helix LT and love it; it's amazing piece of hardware and I recommend it to everyone. I bought it with the intention of using the amp modeling with headphones while my fiance works at home and for recording. I knew that eventually i'd try to incorporate it into some of my amps with the four cable method to get the preamp growl with my favorite speakers. Unfortunately, with both amps, I'm getting miserable hum - Sunn Beta Lead (ss) and Orange OR15 (tube). I've tried multiple guitars, multiple cables, and different electrical outlets. I've ensured the amp and Helix are sharing the same power strip (EMI filtering) and have tried two different power strips. My signal goes guitar -> Helix LT (processor chain one) -> Amp Preamp -> Amp Effects Loop Send -> Helix LT (modulation, processor chain two ) and 1/4 output -> Amp return. The only thing that helps is to put a Noise Gate block into the effects chain within the Helix and set it to about -35db. However, when I strum a chord, the hum is present with the guitar and it's sounding crap. If I try the noise gate in the signal between guitar and Amp preamp no hum reduction occurs. I'm considering the EBTech Humx ($80) or Behringer MicroHD HD400 Ultra-Compact 2-Channel Hum Destroyer ($35) based from other threads. Line 6 Community - based on my experience of hum within the effects loop of multiple amps and it being only tamed by a Noise Gate block - any recommendations? I'm only playing at home and want to be cost efficient. Thanks guys! Quote Link to comment Share on other sites More sharing options...
