Aguilar Tone Hammer Preamp / Direct Box

A Classic Reimagined: the Aguilar Tone Hammer Preamp delivers the iconic Aguilar sound with modern updates for today’s bassist. Renowned for its warmth, punch, and versatility, this preamp/DI is equally at home on stage, in the studio, or in your practice setup.

The Tone Hammer features a 3-band EQ with fully sweepable mids, offering complete tonal control. The updated Drive circuit now includes a dedicated knob and footswitch, expanding the range from subtle grit to full-on growl. With 18-volt operation for maximum headroom, this unit ensures clean, dynamic response at any level.

Practical enhancements make the new Tone Hammer more flexible than ever. It now includes a headphone output and aux input, transforming it into the perfect practice tool. The pristine DI provides a balanced signal with ground lift and pre/post options, while the unbalanced output can drive a power amp directly. From vintage warmth to modern edge, the Tone Hammer adapts to any style with ease.
