You know that moment when you hear a certain sound, instrument or piece of gear that leaves you with your mouth wide open. That was exactly my experience when I heard this wonderful passive tube equalizer for the very first time. From that very moment I knew I had to have one for my studio! What this thing can do to the high-end and low-end of your signal is simply mind blowing! I designed this chassis kit following the original specs of a vintage unit and it not only includes all holes and cutouts for every single component needed, but also 2 filter enclosures to be mounted to the back of the main chassis. These boxes will house the passive filter units that are a vital part of that special sound character. With this chassis kit, the included BOM and the wiring layout, you can re-create the holy grail of vintage tube equalizers for yourself!
