The AG 500 is Aguilar’s most versatile head, featuring two foot-switchable preamp channels and a fully adjustable Saturation circuit. Channel one’s 4-band active EQ provides full, clear tones while Channel Two’s 3-band shelving EQ and Saturation circuit give the bassist everything from tube-like grit to full on dirt. Backed by 500 watts and weighing only 18 lbs, the AG 500 is one of the most powerful portable bass amps made.
