What the AI looks for in Electric Guitar Preamps

Cabinet simulation output
Use the cab-sim or IR output when going direct, and bypass it when driving a power amp and real cabinet. A preamp without cabinet filtering sounds harsh through a PA.
Power supply
Check the required voltage and current draw against your pedalboard power supply. Digital preamps often draw more current than a basic supply provides.
Stereo and IR loading
Check whether the unit can load third-party impulse responses and whether it offers stereo outputs. These features decide how flexible the unit is for recording.

Brands that matter

  • Strymon: Iridium amp and cabinet pedal.
  • Tech 21: SansAmp analog preamps.
  • Universal Audio: UAFX amp pedals.
  • Two Notes: Cabinet simulation and IR products.

What to avoid

  • Running a preamp with its cab sim on into a real cabinet
  • Underpowered daisy-chain power supplies

Questions

Can a preamp pedal replace my amp?

For direct recording or playing through a PA, yes. To drive a guitar cabinet you also need a power amp.
