"The unit is fully working and in good cosmetical condition for its age with some cosmetical traces of use in the wood case. The only thing to report is that the on/off switch button in this unit is not working. So, to turn the drum machine on and off you simply have to unplug the drum machine! Inside the drum machine there is something that moves (a screw or something else), but - since the drum machine works well - we never decided to remove it. Real vintage gem from Italy: grab a bargain!

DESCRIPTION: The Welson Super-Matic S12 is a vintage Italian analog rhythm box drum machine with 12 preset rhythms. Produced in early 70's, it has 4 pads to trigger 4 sounds: Roll Drum, Claves, Tom 1 and Tom 2. Then it has 12 different rythms: Waltz, Tango, Western, March, Samba, Mambo, Bossa Nova, Swing, Shake, Slow Rock, Rythm and Blues and Metronome.

It has a potentiometer to control the volume and another to control the tempo.

It has 4 push buttons (pads trigger) that allow you to play 4 different types of percussions at any time (Roll drum, Clave, Tom1 and Tom2).

It has a START/STOP and an ON/OFF switch (IMPORTANT: in this unit the ON/OFF button is NOT working: so, to turn the drum machine on and off you simply have to unplug it!).

It also has a light that turns on when you turn on the Super-Matic and that flashes with the frequency of the rhythm (set by the tempo potentiometer).

It also has a tone and impedance control potentiometers in the back!

Welson was the Italian brand that produced many legendary instruments. The Company was based in Castelfidardo (Marche, Italy), in the same area where Eko, Elka, Elgam, Farfisa, Crumar, Jen, Siel, Solton, CRB, etc. were born."
