Bassists who dig delicious, tube-style grind are going to be super stoked about the incredible-sounding new Orange Amplifiers OB1-300 and OB1-500 amps. These class AB behemoths feature toroidal transformers, incredibly wide-ranging EQs, and a badass new harmonics section (two right-hand knobs) that really transform the tone from fat and vintage-y to bowed-rattling buzz.
