The Rhodes Mark 7 is a modern design of the classic Rhodes electric piano. It has the look and sound of the classic pianos, but has the look of a modern instrument and shares the luxuries you would get when you get a newer instrument. In terms of tone control settings, the Rhodes Mark 7 has knobs for volume, three knobs for EQ, and a knob for controlling the tremolo effect. All of this is enclosed in a very well made and sturdy casing and I would think that one would have a pretty tough time breaking this instrument. It comes in three different sizes in terms of the number of keys, coming in with either 61, 73, or 88 keys. No matter which option you choose, the feel of the keys is awesome and is really always a pleasure to play because of its easy to play feel. The sound quality of the Rhodes Mark 7 is everything you would think it was and then some. It does just about a perfect job of getting the traditional Rhodes electric piano tones and then has more control settings than the originals do so you can get a wider array of different tones. The tremolo effect is awesome and I tend to have it on most of the time that I am using it because I like it so much. The price of the Rhodes Mark 7 is reasonable considering the great electric piano that you are getting that you can really have for a lifetime if it is treated properly. This instrument is designed for professional players looking for the best they can get regardless of the price, and this certainly fits that bill. All in all if you are a fan of the classic Rhodes piano series, you will not be disappointed by the Rhodes Mark 7.
