Hughes & Kettner Tube Rotosphere MKII The Analog Leslie Simulator
Unknown brand · pedal
The Hughes & Kettner Tube Rotosphere MKII is an analog Leslie speaker simulator built around a real 12AX7 tube preamp, reproducing the swirling doppler pitch and volume shifts of a genuine rotating-speaker cabinet rather than a digital emulation. It offers fast and slow rotor speeds with a breaker-style switch to move between them, plus a rotor balance control that shapes the high-frequency versus low-frequency mix the way a real Leslie's horn and drum rotate at different rates. In stereo it produces a wide, three-dimensional swirl with real tonal complexity and depth; in mono it still delivers a convincingly organic, warm rotary wash rather than a static chorus effect. Separate guitar and keyboard impedance and EQ settings let it sit correctly in either signal chain. It suits players wanting authentic, tube-driven Leslie character for organ-style rock, blues, and psychedelic tones without a physical rotating cabinet.
