Pickup / Guitar & Bass Swap
Drop two takes of the same material — one on the instrument/pickup you HAVE, one on the instrument/pickup you WANT — and this derives a correction IR that translates A toward B. Load the result BEFORE your amp. Think of it as a fun toy for hearing how close two guitars or basses can sound to each other, not a precision modeling instrument.
Before you record
Same material, same order, same steady pace, on both takes — that one rule matters more than tempo, gear, or exact length. Nothing needs to be sample-accurate, but a metronome helps keep pace consistent between takes. Use the same instrument cable, interface, and input gain for both takes, and don't touch your amp/interface's tone or volume knobs in between. No plugins on either take.
Play the same things, in the same order, at a steady pace, on both instruments.
Minimum — start here (about 25–30 seconds per instrument)
This alone rescued a previously-failing real pair (41.6% closure, up from a blocked −21%) — it is the default path, not a fallback.
- 1. Open stringsEvery string open, low to high, one clean pick each, let it ring for about 2 seconds.
- 2. Twelfth-fret stringsThe same six strings fretted at the 12th, same low-to-high order, same clean pick and ring.
Better — add attack variance
Not yet measured on real takes, but should stabilize the correction across pick dynamics and level-dependent character.
- 3. Soft passRepeat the minimum pass (open strings, then 12th-fret strings) picking softly throughout.
- 4. Hard passRepeat the minimum pass once more, picking hard throughout.
Best — the full script
Validated territory: 56–84% closure in the original experiment.
- 5. ChordsA couple of familiar chords, strummed once each, letting them ring.
- 6. A short riffWhatever you actually play — same riff on both takes.
When results get unpredictable
- A tuning or gain mismatch between the two takes.
- Different material played in take A vs. take B.
- Cross-instrument swaps (different scale length or string set) carry a note-dependent residual — this method averages across the fretboard rather than matching per string.
- Active pickups driven into clipping.
