Cracking clean bass preamp which is what I used it for but it shines in its original role as guitar distortion pedal. I actually only plugged it into a guitar yesterday for the first time and it sounded class - I got some killer chuggy, drop d sounds and could dial in a pretty mean thrash tone too.
If I played guitar in a band I’d have this on my board. Can do lower gain too and there’s heaps of videos on you tube. Here’s one with the pedal designer. I love this range of fender pedals - they all have that extra wee features which comes from intelligent design by an actual guitar player.
