It's just a boost with some EQ. I saw it a while back and thought it was hilarious. When the need for a boost came up, I jumped on one.
Sick Set, Dude is a super high headroom clean boost with bass and treble controls that can add punch and clarity to your tone, and flexibility to your rig. The boost runs on 30V internally and can handle boosting other pedals with ease. You can also run it in your amp's effects loop for extra tone shaping options. Quick and easy lead boost, tighten up your bass and add punch in low tunings, add a glassy top end to darker instruments, and more.
The graphics on Sick Set, Dude are an homage to the well-known tour trope of folks asking to use your gear because they forgot theirs, or yours is better, or they're just too lazy to bring their amp in from the car. A little humor on your pedalboard is always fun!
I could always switch to a mini pedal to save some room, but since the boost is the only pedal I use that I will hit during songs, I find the wider target helpful.
