I’ve got a Zoia and I want to run it into a ”pedal” that will power headphones. I’ve searched but not come across what I’m after. I’m assuming some sort of stereo preamp must exist with a headphone out. MUST HAVE 1. 9v C- power that can be run from a One Spot or similar daisy chain. 2. Stereo in. 1/4” jacks. 3 Headphone out. The closest I’ve found have been designs by Saturnworks and OBNE. Neither are stereo. I’m open to a mini-mixer or preamp if the power supply is 9v but most of what I’m finding is 12v and up. I’d be interested up to about $150 before I start losing interest unless it’s a device with some extra interesting features. Show me what you got!
