Based upon the tremendously successful EL DIABLO 100 tube head, we have added elements from our proprietary GFLEX cabinet design to deliver monstrous output and tone in a combo package.

The flexed baffle design, dual GBE 1240-V75 loudspeakers and specifically engineered Focus-Port delivers the huge, thumping sound you'd expect from an EL DIABLO combo.

This unique design of this combo offers all the features of the EL DIABLO 100 head.

The EL DIABLO 100 Combo, is an EL 34 powered 100/50 watt tube head from Genz Benz. Finally, an amplifier with the tone, expression and features worthy enough to match our "world class" guitar enclosures.

Only from GENZ BENZ will you find such well-appointed and bulletproof reliability that is the heart of this DEMON!!

From the flick of the POWER ON toggle switch, the liquid blue glow is an expression of this tone machine's warmth and uniqueness. The design of the tube power section is capable of utilizing EL 34's, 6L6's or 5881 power tubes to suit each player's artistic pallet.

Also, lurking inside this beast is a dual channel tube preamp platform, with the incredible capability of 12 unique and distinctive remote tone variations, easily accessible by the 5 button footswitch. Additionally, an Accutronics (R) long pan reverb is aboard for added lush character.

Even when it comes to transporting EL DIABLO, our unique "EDGE LIFT" handles will give you the assurance of total control over this road-worthy amplifier.
