With 7 isolated outlets and the ability to handle 9, 12 and 18 volt DC pedals plus a 12 volt AC box, T-Rex FuelTank Goliath will power almost every pedal you own – and then some. Each of Goliath’s standard outlets delivers a mammoth 450 mA of 9 or12-volt power – which is enough to keep even the most demanding T-Rex pedals pumping out the tone.
