Design Notes
Our unique incarnation is inspired by two variants of the famed vintage unit. In the late 1970's Pulse Techniques, Inc. debuted a solid state version of the famed EQP-1A3 that featured an API 2520 discrete op amp to provide make-up gain for the passive EQ network instead of the usual tube amplifier. There was also a rare version (EQP-1S3) that offered 5 and 10 kHz high frequency shelving settings. We created a hybrid of the two and integrated an expanded set of passive shelving filters with a 2520-powered make-up gain amp to yield a combination that pulls high frequencies effortlessly to the front of any track or mix.

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.

Great Socks
Color: (001) Black / Black / Castlerock, Size: Large
I keep ordering these over and over again. They fit well, and are soft and comfortable. My feet don't sweat like crazy while wearing them. The cupped heel makes them fit even better. They hold up to everything from everyday use to active lifestyles.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape. My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days. That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.
