Focusrite Liquid4Pre For Sale #1. Serial number lqfp0040x.
We bought this and another of its kind from the Scissor Sisters studio along with lots of synths and other gear.
This one's been sold, but please search our site for Focusrite to see if we have another.
When we got this unit, we had our tech open it to inspect it before powering it up, as we normally do. He discovered that it had been repaired at some point and pointed out a burnt circuit board trace, some replaced capacitors, and a rewired power regulator leg, indicating this unit had been repaired before we got it. The repair looked good so he powered it up and tested it and it appears to work just as it should.
