This is a great preamp case. I got it to match my F6 amp case and to house my B1 Buffer with Korg Triode PCB + Fairchild JFETs kit. Also from the DIY Audio Store. It is still in process, but going together well. Superb circuit board. Really like the 12mm think front plate, has a real excessive hi-end look. All the panels are fitting together well. Super happy with it.
