Aguilar Tone Hammer Preamp and Direct Box Bass Effects Pedal

Based on 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 Aguilar introduces the 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. Separate Gain and Master controls allow you to dial in just the right gain structure for any instrument. The Tone Hammer® is the essential preamp/direct box for every bassist's tool box.
