What the AI looks for in Bass Guitar Amplifier Heads

Rated power at your load
Check the output at the impedance you will actually run (4 or 8 ohms). Many heads make about half their rated power at 8 ohms. The headline wattage usually assumes a 4-ohm load.
Minimum impedance
Most heads accept 4 ohms minimum; a few support 2 ohms. This sets how many cabinets you can safely connect.
DI quality and options
A balanced XLR out with pre/post-EQ and a ground lift. Front-of-house usually takes the DI signal.
Class-D or tube
Class-D is light and powerful; all-tube heads are heavy and need maintenance. This affects portability, reliability and tone.

Brands that matter

  • Aguilar: Tone Hammer heads have warm, musical EQ.
  • Markbass: Compact class-D heads.
  • Darkglass: Modern drive built in.
  • Ampeg: Portaflex for portability; SVT for the classic tube-style sound.
  • Gallien-Krueger: The MB line is light and punchy.

What to avoid

  • Running a head into a load below its minimum impedance.
  • Judging power by headline watts without checking the impedance it is rated at.
