Guitar & Bass Intonation Check
Drop one take — each string open, then each string at the 12th fret, same order — and this measures how sharp or flat every string reads at the 12th: sharp means move the saddle back, flat means move it forward. It's a measurement aid to point you in the right direction, not a luthier — always finish the job by ear with a proper tuner.

Before you record
One take, two passes — the same minimal script that alone rescues a previously-failing real pair over on the pickup-swap tool. Nothing needs to be sample-accurate, just clean and in order.
One clean pick per note, let it ring, keep the order.
- 1. Open stringsEvery string open, low to high, one clean pick each, let it ring for about 2 seconds.
- 2. Twelfth-fret stringsThe same strings fretted at the 12th, same low-to-high order, same clean pick and ring — about 25-30 seconds total for both passes.
