API 550B Discrete 4 Band EQ for 500 SeriesBased on the API 550 EQ from the late '60s the 550b is an update to the classic EQ that played a major role in the history of music recording but adds an additional filter band and several new frequencies. Incorporating API's exclusive circuitry and proprietary components (such as the legendary API 2520 Op Amp), the 550b artfully blends the past with the present. So many hit records still depend on the unique 550 sound that engineers around the world

Too tight at opening
Size: 13 Little Kid, Color: Light Pink
I bought a size larger for my child, and the foot won’t go in. Her other sketchers slides are great. But I do not recommend this model.

Fits good just needs a light ironing.
Good fit with a casual look. These are a nice fit with an almost slim fit width at the bottom. I am a short guy and the 34x28 size fit me great. As I obviously don't have a trim waistline, I like that the bottom of these are narrower than a more dressier pant. The waist of my pants tend to move up and down approx. an inch to inch and a half and slacks tend to get under the heel of the less clunky modern dress casual shoe. Comparison below. Amazon Essentials 34x28 were a lot tighter (like a 32)in the waist and the length seemed loo long.
