Just installed an Invader in my Epiphone korina Explorer and something doesn't sound right. I'm using a POD 2.0 and when I plug in direct it sounds muddy and there's no sustain. I mostly use the Brit Hi Gain and Rectified settings and I was getting a classic Gibson sound before I installed this pup. My Epiphone JR. which has a Screamin' Demon and my Iceman which has Ibanez Super 80's sound WAY different from the Invader. However, when I hook up the MXR Wylde Overdrive the Invader really shines. Is the Invader designed only for super hi gain amps and not so much for the POD? Did I make a mistake?
