There are no bad things I could say about this instrument. It`s just awesome looking and sounding piece of music gear. It`s nice built all covered with nice metal chassis. Control desk is coverd with glass pane with lighting mellotron logo. On the desk you also find two nice looking displays with really nice graphic.
It includes huge bank of sounds. Sounds are based on various types of classic mellotron machines, it goes from classic 70`s sounds to some more real sounding instruments. You can set two sounds at once and then mix them together using the A-B knob which helps to even bigger variety of sounds.
I love to use Mellotron in studio. It just works with any song and any genre. Sometimes I use also external effects (delays, reverbs, modulations, drives etc.) plugging it into guitar amp. It`s pushing this instrument to the whole new level and the sounds are like from not this world, just so inspiring!. Can`t wait to use it also live.
