The Celestion G10 Greenback, with an 8-ohm impedance, is a 10-inch guitar loudspeaker designed to produce a classic rock tone. Developed after extensive listening tests with Celestion's 10-inch ceramic drivers from the late '60s and insights from the original G12M Greenback, Celestion engineers have crafted a speaker that embodies the Greenback family's sonic essence. It features the same rich, warm character and produces a tone reminiscent of the original 12-inch G12M Greenback's iconic "sports-car growl." 

The guitar speaker is designed to emulate the iconic sound of Celestion's 1970s 10-inch models, known for their robust tone. Despite its lower output, it delivers the substantial low-end balance typical of a 12-inch speaker. The G10 Greenback boasts a sophisticated mid-range and a smooth, vintage high-end. In compact setups, it contributes a touch of elegance, and when used in a 4x10 configuration, it produces a gutsy, full-bodied sound with a strong low-end presence.
