I've been thinking about picking one of these up for a while, but looking through YouTube reviews, etc., it seems to be REALLY hit & miss. Some reviews it sounds great, others it sounds like a dark piece of cardboard. What's the deal?? I absolutely love my Precision Drive, so naturally I'd like to try something else from Horizon. What I did notice is that most reviewers that got a great tone out of it weren't actually using it as a preamp, but as a distortion pedal in from of their amp's existing preamp. When used as an actual preamp going into the FX loop return, it sounds, well.... pretty bad. How have people here gotten along with it? Since it can be run on a 9v, I'm honestly hoping to use it as a portable / travel-able "rig in a box" & just run headphones out of the line-level output.
