5. Boss GT-100
The absolute king of the Boss multi-fx range, with the highest quality patches (400 of them) and offering more than just effects, it also extends to amp modelling.
It is the comprehensive rig in a box from Boss, and continues the legacy of the incredibly popular GT-10. Some guitarists use multi effects to add an extra dimension to their existing pedalboard, but the GT-100 is more for those guitarists who want an all-in-one solution.
You can pick it up, pack it up, take it from one gig to the next and you know you've got everything sorted. You knew it would appear on this list somewhere, and our readers voted it at number five.
