Refer all service to qualified service personnel Always unplug the amp when changing the power or preamp tubes Never touch the tubes if they are still hot Always wait to move the amp after use until the tubes have cooled This will prevent tube damage and extend tube life A few minutes should be sufficient While we have made every attempt to outline all general cautions the ultimate responsibility for safe operation of this or any amplifier product rests with the consumer Common sense should be practiced at all times when using the amplifier AMPLIFIER OVERVIEW The GENZ BENZ EL DIABLO 60 contains a unique combination of circuits including vintage tube circuits carefully engineered hot rod tube circuits and advanced tone shaping techniques EL DIABLO 60 delivers unique tone drive and versatility which is exemplified by the 10 distinctive tone variations easily accessible through the four button footswitch included This flexibility allows endless possibilities to craft your own personal repertoire of tone and expression The unique PENTODE TRIODE design of the tube amplifier adds to the versatility of the EL DIABLO 60 essentially 2 different amps in one In the 60 watt PENTODE MODE the amp responds with its bold spanky rich clean tone and classic overdrive sustain all the way into aggressive Hi Gain brutality and all points in between With the 30 watt TRIODE MODE the El Diablo 60 produces a more vintage fuller fatter t
