The Bogner Triple Giant is a three-channel rack-mount preamp designed by Reinhold Bogner, whose modifications of vintage Marshall amplifiers had already made him legendary in high-gain boutique circles before forming his own company. The Triple Giant offers clean, crunch, and lead voices with the harmonic complexity and dynamic sensitivity that define Bogner's design philosophy — where extreme gain does not come at the cost of musical expressiveness. It was a prominent piece in the rack systems of high-profile rock and metal guitarists of the 1990s.
