Andes
Andes is an open source PCB design by niektb: a 2-layer, 40 × 110 mm board with 109 components (29 distinct parts). It is built around the TL072CD, MCP6002-I-SN, TL074CD, LM4040DBZ-10 and more. Filed under audio.

06-11-2024: A new revision of the Andes 8HP is made and this seems to have resolved the issues!
25-01-2025: We discovered that the output has a bit of DC offset and that the knob range isn't utilized in full. Luckily, it's quite easy to improve this. It only require 2 resistors to be replaced with a different value. See the image.
02-02-2025: Changed schematic to reflect this. Also sync 12HP version with changes from 8HP version.
