When I recorded my Strat and the Germino, I found that my Zoom H4 captured the sound really well right away. I cannot get close to what I am hearing in the room when I try and record my Les Paul and Germino + pedals. In the room, I hear lots of dynamics and bite, but when I listen to what I am capturing on the H4, it sounds flat, compressed and lifeless. I have tried adjusting the input volume, but still haven't found the fix. Is it harder to capture tones with more gain?
