i don't know what you mean by a multi...it only does distortion,that's all it was made for,but it has different types of distortion.i used the metal setting of course,but it also had combo,blues...a couple of others...i would tell you more,but i can't seem to find where i left it
but it is a large red and black stompbox style made out of heavy duty plastic(super tough) with a circular knob to select the type of distortion,plus gain,bass,mid,and treble control knobs
on the top it simply says "zoom driver"
i can't even find a picture of one online
