When you need the most presence out of your rig, bass amp heads deliver full tones and big sounds without having to sacrifice tonal fidelity or volume. Whether you're gunning for the classic warmth of a tube amplifier pumping 12AX7s and 6L6s or a modern solid state model capable of producing beefy tone in a more durable build, bass heads lead the charge in your campaign for tone. The right unit is one of the key elements to achieving a signature tone like the percussive slap of Flea or the low, mean rumble of Rob Trujillo. Find all the best new and used heads here on Reverb.
