## Part 4: Chain Architecture

```
Bass → NAM Model (preamp/amp) → Cab IR (bass-specific) → Output
```

- **Pedal captures** (SansAmp, Darkglass B3K, Tone Hammer) need a bass cab IR after them
- **Amp head captures** (SVT-CL, GK 800) also need a bass cab IR
- **Full rig captures** already include cab — skip IR
- **Compression** should be before the NAM model (not modeled by NAM)
- All captures are from Tone3000 — download URLs in full report

### No BDDI v2 / No SVT-VR
- BDDI v2 NOT found; v1 is close (different headroom/EQ curve)
- SVT-VR NOT found; SVT-CL is equivalent (same circuit, different era)
