AMP MODELLING
Digital recreation of amplifiers, cabinets and mics, either in a plugin or inside the amp itself. It is what lets one small combo hold thirty voicings and send them over USB.

Key takeaways
- Digital recreation of amplifiers, cabinets and mics, either in a plugin or inside the amp itself.
- It is what lets one small combo hold thirty voicings and send them over USB.
- It is why a small modern combo can hold dozens of voicings and send a recordable signal over USB with no microphone, no room noise and no volume.
- Record a modelled amp over USB at midnight and you get a usable take with none of the mic placement or neighbour problems of a real cabinet.
- Watch out: auditioning models at bedroom volume and judging them as fixed.
Quick checklist
- Can you define amp modelling in one sentence without looking?
- Can you point at amp modelling in a real session, mix or contract?
- Have you tried the practical move above at least once?
- Would you catch the common mistake before it costs you a take?
- Have you opened one of the primary sources below rather than a forum thread?
AMP MODELLING IN DEPTH
Amp modelling recreates amplifiers, cabinets and microphone placements digitally, either in a plugin or inside the amp itself. It is why a small modern combo can hold dozens of voicings and send a recordable signal over USB with no microphone, no room noise and no volume.
How it works in practice
Record a modelled amp over USB at midnight and you get a usable take with none of the mic placement or neighbour problems of a real cabinet.
The mistake people make
Auditioning models at bedroom volume and judging them as fixed. Modelled amps respond to pickup output and playing dynamics much like real ones — try your own guitar before deciding.

Amp modelling belongs to gear, instruments and tools in the Sampled music glossary. The boxes, controllers and sample formats a producer is expected to know by name — from the MPC to a one-shot.
