With nearly infinite control over EQ and gain structure, the Peavey Pro VB-3 bass amp head is the perfect centerpiece for your tube bass rig. This 300W, 37 lb. amplifier uses a vintage 3-band Baxendall mid-cut EQ, in conjunction with a 9-band, constant-Q graphic EQ and Bright/Low Cut to allow for virtually any EQ curve imaginable without the complexity a parametric equalizer.
