Hammer out your tone with the Aguilar Tone Hammer Preamp / Direct Box, based on the OBP-3 preamp. Bend the rules and blur the lines between pedal and direct box with the Tone Hammer's EQ knobs, Gain and Master controls. 18v of power give you tons of headroom to play with, giving you the freedom to experiment dynamically. The Tone Hammer's unique Adaptive Gain Shaping circuitry even gives you an extra gain structure, so hold on tight.
