Simply, a consumer level Juno 106 with built in speakers and amplifier. It's quite a bit uglier but sounds all the same. Marketed for the home user hobbyist. It even has a sheet music stand option. It's cool if you can find one because it's like a portable Juno 106 that you can play anywhere with those built in speakers! Another feature of this synth is its stereo MIX IN, a stereo input for jamming with other sources of music through the internal speakers. If you're going to use the HS-60 in the studio, you'll need to insert a 1/4 inch plug into the headphone output to bypass the internal speakers since they will continue to output sound when a plug is inserted into only the main audio outs, and this can be quite annoying for studio work. - http://www.vintagesynth.com/roland/hs60.phpmore
It's a Juno 106 with speakers. Some say the additional circuitry for the amp affects the tone of the synth. I've never heard an A/B comparison. It sounds great either way. These are high maintenance synths if they haven't already had the voice chips restored or replaced and the power supply recapped. Be prepared to either pay for service or learn a thing or two about electronics and soldering. It's actually a pretty straight forward thing to work on.
