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.
