5 Common Beginner Mistakes the First Time You Run NAM

Mistake 1: No IR after an amp-only model

Symptom: a harsh, buzzy, "angry bee" sound, especially with distortion.

Why: many NAM files capture only the amplifier, without a speaker cabinet. A real amp is never heard without a speaker — the cabinet filters out the harsh high frequencies.

Fix: load a cabinet impulse response (IR) in the NAM plugin's IR slot or in a separate IR loader after it. Read more in What is an IR and when NAM needs one.

Mistake 2: Two cabinets in a row

Symptom: a dark, boxy, muffled tone with no clarity.

Why: the model is a full rig capture (amp + cab + mic), and you added an IR on top — so the signal goes through two cabinets. The same happens if your DAW template or multi-effect already has a cab block enabled.

Fix: check the file description. For full-rig captures, switch the IR off. See How to read a NAM model description.

Mistake 3: Input level too low or too high

Symptom: the high-gain model sounds weak and clean — or a clean model breaks up and clips.

Why: a captured amp reacts to how hard you hit it. Your guitar, pickups and audio interface gain all change that level.

Fix:

• Plug the guitar into the interface's instrument (Hi-Z) input.
• Set the interface gain so the loudest strums peak well below clipping — no red lights.
• Then adjust the NAM plugin's input knob. If the model and plugin support input calibration, set your interface's input level there for a more accurate response.
• Use the output knob only for volume — it does not change the tone of the model.

Mistake 4: Effects in the wrong order

Symptom: delays and reverbs become a distorted wash; the noise gate cuts notes off.

Fix: build your chain like a real pedalboard and amp:

1. Tuner → noise gate → compressor → overdrive / boost (or a NAM pedal capture)
2. NAM amp model
3. Cabinet IR (only for amp-only models)
4. EQ → modulation → delay → reverb

Delay and reverb placed before a high-gain amp get distorted too — sometimes useful, but rarely what beginners want.

Mistake 5: Audio settings causing crackles or delay

Symptom: clicks and pops, or a noticeable delay between picking a note and hearing it.

Fix: use your interface's dedicated driver (ASIO on Windows), run the project at 48 kHz, and find the smallest buffer size that plays without crackles — often 64–128 samples. If your computer struggles, try a smaller model size (Lite or Feather). Full details in Latency: buffer, sample rate and CPU.

Bonus: comparing at different volumes

When you compare two models, match their loudness first. Our ears almost always prefer the louder one, which makes fair comparisons impossible.
