    Detail

    1. A control panel photographed close

      Fig. 01

      One knob per parameter. Nothing is two presses deep in a menu.

    2. The inside of an instrument on the bench

      Fig. 02

      Six screws and the back comes off. The schematic is on the site.

    3. An aluminium case under studio light

      Fig. 03

      Bead-blasted aluminium, anodised. It marks, and it is meant to.
