Serge Modular Precision Oscillator (PCO)Random*Source delivers a Eurorack version of a classic member of the Serge modular catalog: the Precision VCO, or PCO for short. Operating on the same, highly stable core as the NTO, the PCO offers a streamlined set of controls and features for a no fuss, powerhouse of a utility oscillator. Coarse and Fine tuning controls allow you to tune the PCO anywhere from 16Hz to 16kHz, but the Low frequency switch bumps the module down into LFO territory,

Great price point for GOTS certified organic cotton swabs. Very happy to find an option not packaged in plastic that is fully recyclable, or you can reuse the container after too! Sort of difficult to put lid back on once the swabs have shifted or once you've used some, but I keep my swabs in a separate container for actually using them, so not an issue for me. I use these for personal hygiene, cleaning piercings, and cleaning up my makeup as well as household cleaning. Tips may not be as plush as others but I don't really notice or care.
