Group / Aux VU (Thanks to JLM for VU buffer design improvements)
Prior to backfill and modutec ledger:

Using adafruit's neopixels for color segmentation and brightness. Plans in the future are to dim or brighten vu's that are solo'd or muted, as well as to 'color flash' as a peakmeter. That may require some A/D conversion. I say may because bufferboards include peakmeter, so it could simply be about assigning MC pins to sense dc --returning to it late game.

By the way... I don't see many people using blind tapped holes in their faceplate projects. Provided metal is thick enough, I can attest they are super helpful at mounting things on the back while making for a clean face, and they really don't cost much more than a standard hole, using FPE.

Backfilling:


VU panel backfilled and Main L/R meters complete:
Modutec Retrofit of sifam VUUsing sifam as template:

Using a dremel (That same thing that PRR says is useless

) to cut template:

Plaining the VU face to be as thin as the sifam (Whew boy, this took a lot of patience):

Completed:

Notching out top

Getting top bar flush with panel


Success!
