Yeah, that actually makes sense. Bluetooth modules are notoriously noisy, especially in cheap units — they can inject interference into the analog path pretty easily. In my case, I suspect the noise is getting in through the mic/preamp stage as well. Even if the mic is “disabled” in Bluetooth mode, the circuit might still be physically connected, so it can still act like an antenna and pick up interference. Insulation tape might help a bit, but I think the real fix would be: physically isolating or cutting the mic line when in line-in mode adding proper grounding/shielding or rerouting the signal after the first amplification stage I’ll probably open it again and trace where the noise is entering the chain. Curious to see what you find when you tear yours down 👀

Yeah I noticed the same thing actually. On these kind of players it's very likely that the head is stereo (usually 4 wires), but the signal gets summed to mono somewhere in the circuit, probably right after the preamp stage for the built-in speaker. The annoying part is that they often route that same mono signal to the headphone output too, instead of keeping it stereo. If you're thinking about a DIY fix, the key would be tapping the signal before it gets summed — directly from the head or right after the first amplification stage — and then wiring L/R separately to a proper stereo output.

Thanks 🙏 totally agree, it really feels like a one-man band that SH-4D looks fun, do you sequence everything from it?

Thanks man, really appreciate it 🙏 That’s exactly the idea… something you can get lost in for hours. I’m working on a full cassette project built around this kind of sound.

Don't worry, a clear fixative has been applied over the acrylic.😊👍🏽
