Ace Tone GT-7 (Hammond), the largest Ace Tone model, made in Japan. It has a 44-key upper keyboard, 44-key lower keyboard and a 13-key pedal. Includes 9 drawbars for the upper keyboard.
It is compatible with the Leslie 760 speaker, a powerful, solid-state 90-watt rotary speaker designed primarily for Hammond instruments, with upper horn and lower drum and three speed modes (slow/chorale, fast/tremolo, stop).
Key technical features
Power approximately 90 watts in total, with two independent solid-state amplifiers: ~55 W for the bass channel and ~35 W for the treble/horn.
Active crossover (not passive as in the 122/147) that splits the signal into upper horn and lower rotor, with a separation frequency of around 800 Hz, so that the lower rotor has enough midrange in addition to low frequencies.
Top driver (horn) for treble and bottom rotating drum with 15" loudspeaker for bass, giving the classic Leslie "swirl" (Doppler effect).

"Instrumental" and practical especially for rock/blues.
