The MXR M83 Bass Chorus Deluxe Effects Pedal is a versatile bass chorus pedal that possesses an abundance of tonal shaping options so you can fully create your own ideal sound. An X-Over mode provides luscious depth whilst reducing the modulation at frequencies below 100Hz ideal for chords in the upper registers. Full tonal shaping is delivered by two individual bass and treble controls which allow your notes to ring with more depth or alternatively dial it up with an increased presence. A brilliant tone and reliable construction with the M83 you cant go wrong.
