Home Studio Recordings Ruined by Environmental EMI/RFI Noise That Can't Be Cleaned Without Damaging Tone

Summary

Musicians and home-recordists are being derailed by persistent electromagnetic/radio-frequency interference (hissing, buzzing, static) that infects every guitar and bass in their space, often after moving to a new home or from nearby electronics. The user in this source tried new interfaces, preamps, cables, amps, and even hired an electrician — nothing fixed it — and explicitly asks for a way to remove the noise WITHOUT noticeably changing the guitar tone (no heavy noise gates or pickup swaps). Current denoisers either fail on this kind of broadband interference or destroy the timbre, and there is no accessible, affordable, tone-preserving cleanup path. This maps directly to the unsolved 'background noise and rough home recordings are hard to clean up quickly' pain — a high-intensity (pain score 9), high-frequency problem for bedroom producers, guitarists, and content creators who need clean stems fast and have no good solution today.
