The Aguilar Tone Hammer Preamp/Direct Box is a versatile and robust unit designed for both studio and stage use. It features fully sweepable midrange frequencies in addition to bass and treble controls, providing studio-inspired EQ capabilities. The proprietary Adaptive Gain Shaping circuitry (AGS) allows for additional gain structure, enabling a transition from modern tones to vintage, tube-like saturation with the push of a button. The unit operates at 18 volts, providing ample headroom to reproduce dynamic playing styles, and its heavy-duty steel construction ensures road-worthy durability.
