Our lightest and smallest head to date boasts an unbelievable power-to-weight ratio (more than 100 watts per pound!). The F1's digital power amp gives it a super-fast response and a crisp, clear, full sound that will convey every detail of your playing, instantly! Although it's tiny enough to fit just about anywhere (for example in your gig bag), there's an optional amp bag and special rack ears available. For speed, choose the F1!
ISP Music magazine of Spain has given the F1 two awards: "ISP Music Selected Product," and "ISP Music Recommended Price."
