# Roland System 100 Model 101 and Model 102 Expander

Roland, System 100 @ 10 June 2018

“Roland System 100
– 101 Keyboard unit
– 102 expander unit

The 102 unit has been modified in a really cool way. The headphone output had been replaced with a switch that turns on a sub oscillator (square wave). The knob is a level control for the sub oscillator. Much more useful than the headphone output, especially when you have both of these units together.

Both are in fantastic condition. Cosmetically very very clean. And working great. ” Click here to visit listing on eBay
