What distinguishes the Rotosphere from the Rotosphere MKII?
The MK II version offers two new features that its predecessor, the first Tube Rotosphere, lacked:
When you stop the rotary action, the simulated drum and horn always return to the same default position. This ensures that varying rotor positions don’t color the sound of the pedal and that you get consistent tone when you use the Tube Rotosphere purely as a tube preamp.

2. A couple of trim pots let you adjust the FAST speed separately for the drum and horn. These two trimmers are located to the left and right of the BALANCE knob. Use a small screwdriver to adjust them. Feel free to try out different settings for the two rotors and dial in the combination of speeds that you like best.
The button that controls the BREAKER function was replaced with an On/Off switch. While the old model required you to hold the button down with your foot to arrest the rotary action, now you can simply activate and deactivate the BREAKER at the touch of a button. That frees up your foot to operate other effect devices or, in the case of organs, bass pedals.
