Ampeg VT-40

A 60-watt guitar combo from Ampeg, originally designed as a guitar amplifier with 4x10 speakers. Josh Homme runs his guitar through Ampeg bass-oriented amps for the thick, woolly low-end and compressed midrange that define the Queens of the Stone Age sound. The VT-40 delivers massive, earth-shaking fundamentals.
