Guitar Amp Simulator (NAM) — workflow

Try guitar tones with NAM models. Check input and model before raising output volume.

  1. Check instrument input and browser microphone permission.
  2. Choose a model and add a cabinet IR only if needed.
  3. Check doubled monitoring and latency; compare the same phrase.

Before you start

An additional IR can dull a model that already includes a cabinet. Latency also depends on the device and interface.

Processing, free limits, and device support

Standard separation, noise removal, and BPM analysis run in your browser. HQ separation, music/loop generation, reference mastering, OCR, and cloud saving send inputs or audio to servers according to the feature you choose.

Standard separation, noise removal, and BPM analysis are free. Autotune and some other tools have free-use limits; HQ and generation features have plan or credit conditions. Check the price shown before running and the pricing page.

Desktop Chrome or Edge is recommended. Features depend on GPU, memory, and browser. Test a short file first, including on mobile devices.

Hear the model and cabinet IR separately

This workflow example uses short synthetic plucks: E2–A2–B2–E3–B2–A2–E2–E2. It is not a recorded guitar DI. The deployed NAM AudioWorklet processed the JCM2000 Crunch model at 0 dB input and −12 dB output.

Synthetic input (8 seconds)

Synthetic input (8 seconds) — WAV

NAM model only

NAM model only — WAV

NAM + 1x12 American IR

NAM + 1x12 American IR — WAV

Outputs include one extra second for decay. The cabinet version uses the built-in 1x12 American IR. No loudness matching was applied afterwards; volume differences alone do not establish quality. This is an offline engine render, not a measurement of microphone latency.

  1. Connect your guitar to an interface’s instrument input and check the selected input and headphone output.
  2. Choose a NAM model and start with low output volume. If the model includes a cabinet response, listen without an additional IR first.
  3. Toggle the cabinet IR and compare the same phrase. Check input and monitoring paths if you hear doubling or clipping.
