The Boss ME-50B multi-effects effect pedal is a worthy investment that is pocket-friendly to either a beginner, intermediate, or pro bass guitar player with all the necessary effects one would need in bass guitar.

Its metallic casing gives it a harder shell to prevent it from damages that may be as a result of the vigorous pressure from the feet during its usage.

The different division of the section is great form easy usage and manipulation while it is being used.

It is divided into 6 different tones that give it its uniqueness and the different tone range these sections include the master, filter/tone, synth/drive, modulation /delay, and my personal favorite the expression pedal.

Your bass effects can be edited using a 23-knob system which is controlled using a 3 built footswitch system with an assignable expression pedal.
