AMPWELD — three amps, one capture

Every great guitar tone I've chased was never one amp. It was a bit of this, a bit of that — the chime of one, the push of another, the weight of a third. NAM captures gave us the amps. Nobody gave us the blend.

So I built AMPWELD. It runs in your browser, it's free, and nothing you load ever leaves your computer.

How it works

1. Load — drop up to three NAM captures (A1, A2 Full or Lite). Each bay reads the file and shows its waveform.
2. Render — a test guitar signal plays through every capture at matched level, so you compare them on equal footing.
3. Blend — the level knobs set the recipe. AMPWELD aligns the amps, balances loudness and mixes them into one target sound.
4. Weld — a fresh capture is trained to match that blend. The ERROR % needle drops round by round while you watch.
5. Save — export a standard .nam, or a file ready to load on an HX Stomp in NAM mode.

How to use it

• Open ampweld.mrdeesmusic.com in Chrome, Safari or Edge and drag a .nam onto each bay. The LOADED lamp lights when it's ready.
• Turn each bay's knob to set how much of that amp you want. HEAR solos a bay; HEAR BLEND plays the mix you're about to weld.
• Pick Quick, Standard or Deep (3, 8 or 20 minutes) and press WELD. Three minutes gets you most of the way. Hold WELD to stop early.
• HEAR RESULT plays the new amp. Flip A/B against the blend it learned from. Switch on LIVE and play through it with your interface.
• SAVE .NAM for any NAM player, SAVE HX STOMP for the pedal. Name it in the display first.

Bonus: drop any .nam onto SAVE HX STOMP and it converts it for the Stomp — no welding needed. Full-size captures get distilled to Stomp size automatically.

The Gilmour tone in my recent videos is an AMPWELD weld — a Hiwatt, a Fender and a clean amp, welded into one capture that lives on my Stomp. Go build yours.
