BossX. I too initally felt that built in speakers just added needless weight. I would always shut them off by inserting a 1/4" jack into the headphone socket. After reading comments from others here who said they liked using the internal speakers for stage monitoring purposes, I realized exactly what they were talking about. Without the built in speakers, you cannot really hear (or gage) what the audience is actually hearing. I now find having built in speakers very useful for both solo gig and stage performance venues. - Scott
