In addition to the 3-way equalizer, it is equipped with "Deep". By raising this, a tight bottom end without muddiness, which cannot be replicated by conventional tone controls, is added, realizing a rich and expansive low end." "It has the same effect as the popular JCM2000's "Deep" switch, boosting the bass and adding a dynamic bass sound without muddiness, which cannot be replicated by conventional tone controls."
