I recently purchased a helix floor. And I got the latest version. I plugged in my guitar and connected the 1/4 out to my audio interface. When I turn the output knob all the way up, the sound is a little tinny, and when I look at the volume meter that shows the output at the end of the helix effect patch, it only goes to about halfway up. The gt-1000 I've been using has a function to adjust the input level, does this one?
