This is a very nice designed full aluminum chassis, with a remarkable quality of finishes, both for the solid thick aluminum faceplate and for the anodizing of the rest of the case plates. Also, the shape and finish of the massive ALU knobs (delivered in the package) is outstanding. For the front plate, the cut-out is exactly dimensioned for 'TEK Vomit backlight white dB with calibration module' (but check with the store support for accuracy), as the front plate has the exactly window cut-out for the TEK Vu-meters, but it also has the necessary cut-out milled on the back of the front panel for the shape of the VU-meter plastic box.
The bottom and back plates are not hard, but very easy to drill/mill for the needed holes. In my case, the chassis hosts a led biased Mu-follower line preamplifier based on E88CC.
Highly recommended!
