Hairball Audio 1176 Rev A Blue Stripe

For sale is 1 Hairball Audio 1176 Rev A (Blue Stripe). This is an absolutely incredible compressor. The original version of this compressor by Urei sells for several thousands of pounds (At the time of posting this there is one listed for £10,000!)

The Rev D (Blackface) version of this unit are far more common and currently in production however the Rev A (Blue Stripe) is the more sought after version and is particularly favoured on vocals. It has a slightly more "coloured" and aggressive sound when compared to its brother.

This unit features the renown ALL BUTTONS IN mode and I've used it on drum rooms with great success.

I built this in December 2017 and was burned in overnight before being put to use in several sessions. The final picture in the listing is the frequency response measured by a Lindos MS20 (Precision testing equipment). 

I have been building audio equipment for the last 3 years and was originally taught to solder by the Royal Navy, so I have confidence by builds are flawless and to date I have not had any complaints or faults in any of the units I've sold (or kept for that matter).

There is a very slight mark next to the attack knob, caused by an allen key slipping during the build. It is barely noticeable and otherwise the unit is in perfect condition.

From the Hairball Audio website: 

Often referred to as a “Blue Stripe”. These units were the first commercial revision and have a silver panel with a distinctive blue stripe over the VU meter. The signal and line amp are based on the 1108 mic pre and use a FET as the first active component in each amp stage (all other revisions use a bipolar transistor). The gain reduction FET in this model has a unique circuitry around it, different from all other models (notably the lack of source resistor). This results in a little more distortion that helps define the “Blue Stripe” sound. This revision also has a slightly lower threshold in comparison to later revisions (about 5db) and more gain in the amplification stages (about 5db) than the Rev D. This revision is rare, limited to less than a 1000 units, and are highly sought after by many engineers and producers.
