I believe the boss has the quarto trigger so yes. There are several small allen screws up in the trigger area. Im not home right now so i cant tell you what each one does but you need to loosen or tighten them to adjust length of pull and pull weight. Small turns to get the feel of how each one reacts. I backed off the pull weight a bit on mine and it breaks at about pound. I could go lighter but it wasnt as crisp.
