Disclamer: usually I don't use the reverb part of the pedal at all, I ended up using it just as great distortion, this is my go-to tone now.
Tone: this one is based on the Iron Horse pedal which is based on the Rat. That saying it sounds quite far from the ProCo Rat I have and differently from Iron Horse which I got for comparison. You can get very close to this sound with Iron Horse, but the tone on Melee is a little bit darker even on the highest setting than on IH. For some reason I couldn't get the exact match and I just like Melee more. Maybe it's because of the nicer picture, I don't know but IH won't replace Melee for me.
I have a Fender Jazzmaster and the tone with Melee is mindblowing. It has this fuzzy texture. You don't even need to crank up the gain for that. I end up using it not more that 30% distortion and that way I can get both the fuzz and the clean clarity of the notes, it's really wonderful.
The Stick: It's the selling point and a gimmick. Getting the exact position is a little bit hard and imprecise, but it works. One thing to note is that it is IMPOSSIBLE to turn the reverb all the way down. It's always there. The best you can get is on the pink program, it's barely listenable, but it's still there. On orange in blue you can hear the tail on short sharp notes more clearly.
Conclusion: buy it. It's a superb distortion plus beautiful picture plus you can get reverb if you need to. This thing stays on my desk.
