Bogner Uberschall Twin Jet Head

The Bogner Uberschall Twin Jet Head was introduced at the 2009 Winter Namm Show and was globally released later that summer. The name TWIN JET refers to having two powerful gain channels on tap versus the more traditional clean and gain channel configuration of our standard Uberschall.

Features of the Bogner Uberschall Twin Jet Head are :

– Newly voiced clean channel which can deliver semi cleans to hot rodded high gain flavored sounds.

– Additional flexibility added to super high gain channel.

– KT88 power amp section with expanded controls.

– White front panel (original black mirror polished panel available as a special order)

The TWIN JET’s new clean channel features the same controls as the standard Uberschall but with an entirely new circuit. You can still dial in clean sounds with single-coil guitars but pure, super clean tones are diminished if using humbucker equipped guitars. This new gain structure now offers you a clean channel that can be dialed in as a second gain channel. While the clean channel’s gain does not match the super high gain of the second channel, it will give you the ability to have semi-clean, Plexi, JCM or hot rodded tones. (Note – in November 2009 a revision to the gain control was made to offer a better clean sound.)

The super high gain channel is identical to the standard Uberschall with the exception that the presence control is now in the channel circuit itself, rather than the power amp. The Uberscall’s power amp presence control is the same as the Twin Jet’s master presence control which affects both channels on the Twin Jet. With these changes the Twin Jet’s super high gain channel’s presence control becomes an additional tone and feel shaping control.

The power amp section of the TWIN JET features a quartet of KT88’s which run on higher plate voltage then the standard Uberschall giving you a raging 150+ watts with more articulation and quick response. Control over the power amp has been expanded via a depth and presence control in addition to the master volume control already found on the standard Uberschall. These controls affect both channels and let you dial in overall low end response and presence.

Our UBERKAB is perfectly matched for the thunderous TWIN JET and UBERSCHALL. This 4×12″ straight front speaker cabinet features a black front speaker grill with silver piping and a combination of front loaded Celestion Vintage 30’s and G12T75’s wired at 16 ohms. This combination unleashes the aggressiveness of the TWIN JET amp, plus helps to maximize the low end and give great cutting power to the mids and highs. Our standard Bogner 4×12″ cabinet, with Vintage 30’s, also sounds great with either the TWIN JET or UBERSCHALL but we wanted to offer a cabinet that was fine tuned for both flame-throwing designs. (Note: prior to January 2009 the Uberkab design was slightly different with speakers being rear mounted and wired at 8 ohms.)
