I need help elimitating input distortion on the Helix.  It happens on all my guitars and on almost all patches.  Was in the studio last week and it was the first thing the engineer said.   Guitars: PRS CE (85/15 pickups), Fender Strat Ultra (Shawbucker), Gibson HP LP, Fender Tele Ultra (stock pickups).  Variax  Input Gate:0n Threshold:-74 Decay:500ms Guitar in-Z Auto Guitar Pad: Global PROMISES.hlx
