If you're utilizing an amp simulator pedal like the Boss IR-2 or IR-200, Line 6 HX, Strymon Iridium, UA Dream/Lion/Ruby/Woodrow, or Walrus ACS1, the IsoFormer™ DUO is the ideal solution for both isolating and connecting your simulator to the front-of-house. Unlike a DI box, the DUO's balanced output signals are not attenuated, meaning less or no gain adjustment will be necessary at the console. You can play with confidence, knowing that the DUO's JENSEN™ transformers and ground lift will keep your tone pristine and completely free of hum.
