The JDK Audio V14 is a 500-series EQ. This four-band EQ has no shelf on the top or the bottom, but you have flexible bands where you control the gain(+/- 12 db) and the frequencies(that cover the range from 20 to 20k). It also has in/out button.
The V14 is not a colored EQ and might be considered transparent, that's why so many people call it a general-use EQ. Personally, I like the top of this EQ especially on plucked string instruments( such Guitars or Ouds for middle eastern people ) where it gives them that "sparkly sound." However, I don't see it smooth, which means it could be harsh when overused.
The price of the unit is very affordable, and probably one of the best EQs that can be found in that range. This what makes this EQ very competitive.
The thing that I don't like about this unit is the building quality. The plastic used in the knobs feels so cheap and so light when you rotate them. But anyway, all of these cons are seen logical when recalling the unit's price.
I highly recommend this EQ for people who want to start their 500-series journey.. nothing to regret
