two bodies: a header containing rotating treble horn and a 2 channel amp, and a database containing a rotary woofer
a remote control gives access to the start of the engines, two-speed switch, régalges two paces (slow and fast) start reverb, reverb choices short or long
simple settings, no manual, but a child would pull
HP rotary inimitable sound unlike a guitar amp "normal", what kind of amp delivers the sound to 360 °, and therefore relies heavily on the room acoustics.
I tested it with an organ, guitar, and ... electroacoustic hurdy-gurdy, feeling warranty, very effective sound installed, groundwater, atmosphere, or slow tempos
I also Elka 700, here we are in the upper range, two bodies, it makes a nice buffet on stage to take, uh, you really want to!
it is rather cumbersome, but the studio is perfect! with a few bonus mechanical noise, belts, motors, the current of air horns that turn, clicks the remote, hmmmm, it's everything but the stereo, it's still a transistor amp, but it has character !
