EMS Synthi AKS W/Touch Keyboard And Prestopatch
⭕ Up for sale is an analog synthizer: EMS Synthi AKS, with KEYBOARD Prestopatch. This synthesizer needs no introduction. It is one of the very early models with the 18 dB/octave filter response, indicating it was built before 1974. This unit has a 30 note touch capacitive keyboard. Keyboard Prestopatch is included. Printed dope sheet of control setting for the patch is in the manual.
This Synthi is all original. Bulb for envelope shaper was replaced, reverb IC was replaced and resoldered wires to the reverb. These repairs were made using parts ordered directly from EMS. This is a vintage machine and as such has the some slight wear patterns and case scratches you would expect in an old machine. The numbers around the levels on channel 1 and 2 have some fading and are not clearly visible. The face plate around the umbilical plug in show signs of wear. Minor fading around the oscillator frequency labels but readable. Closing the case is tricky, the ABS bottom portion where the keyboard is housed for travel, has a slight warp and must be pulled slightly to fit into the ridge for proper closing. Included is the manual, power cord, umbilical cable, and an EMS synthesizers bumper sticker.
