You know it when you hear it. That instantly gratifying sound that hits you right in the gut. Professor Punch-Knuckles from Softube and Empirical Labs delivers just that: warm and gentle saturation all the way to forceful and explosive character for your drums, vocals, and more. All with the unmistakable and unique sonic character of ELI.

Highbrow hellraiser 
If any tool is going to make it on the very short list of once-in-a-decade modern classics, it’s the Empirical Labs Distressor. Since its inception, and 1995 release, Dave Derr's Distressor circuit has also been included in other ELI products, such as the versatile preamp/compressor Mike-E.

Professor Punch-Knuckles is the brilliant but unruly lovechild of Mike-E and the Distressor. But don’t let the analytical, professorial side of Professor Punch-Knuckles fool you, it can crush your audio to pieces. Smooth, warm, and musical, Professor Punch-Knuckles is a punch in the gut – with honors. 
 
Three classic Empirical Labs saturation flavors 
Professor Punch-Knuckles is more than just brute force. Its sophisticated side lies in three distinct types of modeled distortion/saturation: Toasty, Crunchy, and Distress. Toasty and Crunchy are based on the saturation and preamp distortion of Mike-E. Distress originates from the compressor circuit of the Distressor and Mike-E.

The easy-to-use interface is the quickest way to take your sound from warm vintage tones, through gentle breakup, all the way to the classic distortion/compression sound of the Empirical Labs Distressor.  
 
Tone Shaping 
To make the sound a punch in the gut, rather than a slap in the face, the Professor is equipped with additional options to shape the sound. These include the unique Mode switch, which employs Empirical Labs’ emphasis filters to the sound. With this mode, users can easily add the recognizable sound of transformer and tape, making the rough punch smoother and more refined. 

In Short: 

  • Three classic saturation flavors 
  • The distortion sound of the Distressor 
  • Tone shaping options including emphasis filters 
  • Easy-to-use and instantly gratifying
  • Console 1-ready

Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves
Size: 16.5 Inch, Color: Rustic Brown
I loved these for my room, they were easy to install and super versatile, I love how easy it was to assemble them and how functional they became once I was done setting them up. They fit perfectly next to each other and I love how my room looks nice since I don't like relying on bookshelves or anything of that category and rather have wall shelves. They are really stable and I love how they look, they are also really easy to clean since I spilled some baby powder from my last waxing session and they clean up pretty well. Overall, just know that these shelves are super stable, durable and versatile, I love how many things can fit on it if you know how to organize or don't have much stuff to put on them; it's all up to you and what you need them for, so I recommend them 10/10!

Great shelves! Had for years!
Size: 16.5 Inch, Color: Rustic Brown, Size: 16.5 Inch, Color: Rustic Brown
I love these shelves, I’ve had them set up both ways, as a floating shelf and the other way where you get some side support. I’ve had them for years, moved with them, and they continue to work great. I’ve had a lot on them too weight wise (I love books) and they don’t cave in the middle. Great shelves and easy to assemble (I’m a newbie with a drill). Great value for the money, durability is great, adjustable, and great for what you get!
