Aguilar Tone Hammer Outboard Bass Preamp

This preamp/direct box is so strong and powerful it could only be called the "Tone Hammer"! Based on the the respected OBP-3 preamp, the Tone Hammer features fully sweepable midrange frequencies in addition to bass and treble controls. With the Tone Hammer's pristine D.I. you are set for the studio or the stage.

To give this tone shaping unit the ultimate flexibility we are introducing our proprietary Adaptive Gain Shaping circuitry (AGS). AGS allows the player to kick in an additional gain structure and EQ with the "stomp" of a button. You can now go from modern slap sounds to vintage or overdriven.

18 volt operation gives the Tone Hammer plenty of headroom to reproduce the most dynamic playing style. Seperate "Gain" and "Master" controls allow you to dial in just the right gain structure for any instrument.

The Tone Hammer is the essential preamp/D.I. for every bassist's tool box.

Aguilar Tone Hammer
By Karlo Abapo
It is a high quality preamp. It does not color your tone. It also is flexible because of the mids and the clarity is sublime. I like it very much but the Aguilar wouldn't suffice if you are looking for an overdriven sound.

The Tone Hammer adds EQ and some optional grit to your existing sound. I use a Sansamp to get a Sansamp sound, and the Hammer to get the pure sound of my basses. The DI is great too.
