There just may not be anything more gorgeous than strapping a pair of Pultec equalizers across a mix and boosting 12 or 16 kHz to add some "air" to the top end. The Rogue-Tec Air is a high frequency boost for the Colour format faithfully based on this legendary passive EQ.

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.

Wow!!!
Size: King
I couldn’t be happier with this mattress cover—it completely transformed my sleep. I had one of the best nights of sleep I’ve had in a long time—no tossing and turning, just pure comfort. It stays in place nicely and feels high-quality and well-made. Fluffy without the bulk. If you’re looking to upgrade your sleep without buying a whole new mattress, this is absolutely worth it. Highly recommend!

Best sleep matress topper
Size: Queen
Ordered after running out of options to get a good night's rest. Placed Q sized mattress topper on a tempur pedic matress and 1st night slept like a baby on a cloud. Ever since then I have knocked out after sleeping and moved less at night. Restful sleep has blessed out house again. It feels like a hotel comfy mattress. Totally recommend.

It’s like a nice hug.
Size: Queen
I find this mattress pad very comfortable to sleep on. I originally bought it because my mattress was too hard. The mattress pad solved the problem. It’s nicely quilted making it very cushy. I’m very happy with it.

Fixed my aches, real improvement in sleep
Size: Queen
It actually does make my bed feel better. I was skeptical, but decided to try it because our mattress isnt very old but I wake up with aches in my hips/lower back. When I got it, I thought no way this works. But it does. It goes in like a fitted sheet, super easy to put on. And I honestly havent woken up with hip or lower back aches since using it. Had it on our bed for about 2 months now. I read some people say they sleep hotter with it, but I havent noticed that at all. Temperature feels the same as without it. So glad I tried this before spending money on a mew mattress!
