I built the wooden cheeks AND two 3HE desktop racks, that '(at the moment) includes a neutrick 24ch patchbay connected to a behringer 1602 linemixer. and i have a bsspod xt ( i know, but i bought it some years ago …) as effects unit and an alembic fx1 to be used for kicks etc. and a dbx 266 for ducking compression.
so far everything works fine, except that the behringer unit was defect, so i they gave me a new one hehe.
to anyone that wants to build cheeks for those synths especially for the analog four :
BEWARE ! ! ! !
if you use too long screws on the bottom left side where the button of the first step is, the screw blocks the button and i dont know if it touches the PCB while blocking the button
i thought my A4 was damaged until i released the screws, so make sure they are just as long to fit in and no mm/inch longer then that
will post some photos, also i can upload a drawing with dimensions in mm/inch, if someone wants do skip that step
