The Cobra 90 is a high-powered guitar amplifier from a lesser-known manufacturer producing equipment for the gigging musician market. Offering 90 watts across dual channels, it was positioned as a powerful workhorse amp for live performance. Cobra amps occupy a niche in vintage amp collecting as examples of the many independent manufacturers active in the pre-boutique era.
