  MIX BUS, MEET YOUR NEW BEST 

FRIEND

Looking for the piece of gear that gives you that elusive “magic” on your mix 

bus?  We were too!  We went through everything from high end summing 

mixers to racks of insanely expensive gear and most of it barely did anything 

(you had to sit on the edge of your seat and strain to see if you could tell the 

difference)!  Even when we did find combinations that got us close to what we 

were after, it meant tens of thousands of dollars in gear and using each piece 

for very little (sometimes using a piece of gear only for it’s transformers).  Most 

frustrating of all, it meant lots of controls with none of them directly focused 

on doing what we were after.  This was 2009 and it became obvious that no 

one made what we were looking for so we created 

Black Box Analog Design

 and 

spent the next five years designing the HG-2.

The HG-2 is specifically and uniquely designed to be an all in one unit capable 

of giving you all the vibe, harmonics, saturation, tonal enhancement and RMS 

you could want on the mix bus.  With simple, intuitive controls, no compromise 

components and unique features not seen on any other piece of gear, the HG-2 

replaces many pieces of gear and simplifies mixing.

From extremely subtle harmonic enhancement of the tubes and Cinemag 

transformers to RMS pushing saturation, full on distortion and natural tube 

compression, the HG-2 is designed to give you full control over the “mojo” on 

your mix bus.  It also happens to sound awesome on instruments and as a front 

end for synths and other stereo sources!
