The powerful Frank Gambale Signature 112 combo combines the warmth and crunch of a tube preamp with the clean power of a solid state one. Like Frank Gambale, it doesn't compromise! DV Mark developed this signature 12" combo to suit Frank's exacting needs. After spending a few hours working with him, they understood and appreciated his concept. He wants to make sure that the power amp is powerful enough to provide clean amplification at high volumes, without contributing to the distortion. Any distortion should come from a tube preamp that's applied to the drive channel only. This way, he can control the amount of drive with his guitar's volume pot or with a volume pedal. The successful implementation of this concept has earned Frank's stamp of approval, as well as his signature! Frank doesn't compromise, and this is why he's one of the world's most respected guitarists.
