The Aguilar Tone Hammer 500 bass amp head brings Aguilar's legendary tone to an ultra-compact package. Based on the popular Tone Hammer pedal, the Tone Hammer 500 combines three bands of flexible EQ, a colorful overdrive and 500W of power—ideal for bassists seeking a lightweight yet powerful solution.

Three-Band EQ Provides Sonic Control

Shape your tone with precision using the Tone Hammer 500's bass, midrange and treble controls. The midrange knob lets you select the center frequency, from 100 Hz to 5 kHz, allowing you to boost or cut the precise midrange band that complements your bass and style. From thick, punchy lows to aggressive highs, the Tone Hammer 500 puts complete tonal control in the palm of your hand.

Adaptive Gain Shaping Adds Distortion and EQ

When you need an extra boost of distortion or EQ adjustment for a track or live performance, engage the Tone Hammer 500's drive control. Aguilar's Adaptive Gain Shaping circuitry subtly distorts your tone and tweaks the EQ curve to add punch and aggression. From subtle grit to all-out grind, the drive control provides as much overdrive as you need.

Class D Power Amplifier Delivers 500W of Punch

Despite its diminutive size, the Tone Hammer 500 pumps out 500W of power at 4 ohms and 250 watts at 8 ohms, plenty for live shows and studio sessions. The lightweight yet robust Class D power amplifier, teamed with an efficient switch-mode power supply, provides powerful, articulate tone with a portable footprint.

Roadworthy and Ready to Rock

The Tone Hammer 500 is ideal for bassists on the go. It slips easily into a gig bag or backpack and sets up in seconds, perfect for clubs, studios and fly dates. An affordable, professional-grade solution for bassists seeking huge tone in a tiny package, the Tone Hammer 500 delivers the legendary Aguilar sound that has made the brand an industry leader.
