Amazing 1976 Fender Dual Showman Reverb STACK! The speaker cabinet features two JBL D130F Speakers. This rig has a sparkling almost piano like quality but at the same time a brutal rock and roll tone. This must one the perfect complement to a middy Marshall stack in a two guitar player setup. We're playing it using a 1978 Fender Telecaster Custom (Single coil and Humbucker) and a 1978 Gibson Les Paul Pro (P90).
