Meet the king of instruments

The American Classic 770 is one of the newest crown jewels in the Johannus family. Draped in a console fit for a king, this majestic organ is adorned with seven divisions, graced with an astonishing number of voices and enriched with such a full range of orchestrals that the unique 64-foot Diaphone seems merely an encore. Have a seat and meet the king of instruments.



For concerts, practice or accompaniment

The uncompromising American Classic 770 from Johannus checks off every item on the American organist’s wish list. This instrument is suited to the whole range of organ music. Concerts, practice and vocal accompaniment: they all go hand-in-hand with the American Classic 770.



Churches, cathedrals and concert halls

Truly appreciate the prestige emanating from this organ, which was designed for churches, cathedrals and concert halls, as you take your place on the bench in front of the instrument and take in the view from left to right.



99 voices

The robust, wooden cabinet is solid and impressive. Its craftsmanship and quality are unmistakable. It takes a while to count all 99 voices on the panel. But you count them again anyway. Are there really that many? You glance back to the resources of the pedal division. Does it really have a 64-foot Diaphone? You continue your survey and notice that it also has seven orchestral voices, plus at least 40 MIDI voices! That’s right: the clarinet, the tuba- the whole orchestra is inside your organ. But there is more: would you like to perform a trumpet tune with a baroque trumpet? Or accompany vocals with a pan flute? A festive improvisation with hand bells? The American Classic 770 has it all.



Seven divisions

The three manuals of the American Classic 770 lay before you. You had already noticed the seven different divisions, but now you’ve grown curious about the fabulous audio system hidden behind them. Building an imposing instrument is one thing, but bringing out the imposing sound of a good pipe organ is quite another.



World-class sound quality

Carefully, you set your registration and take a deep breath, wondering if this majestic organ can make it all happen. And then it does! The imposing sound of a fine organ emerges from the organ’s 76 speaker drivers. You are enraptured by your own music. 28 perfectly balanced external speaker cabinets ensure that even the sweetest flutes mix harmoniously with the deepest-bellowing pedal tones. And the attack! What you hear is not a simulation, but rather the pure speech of pipes.



Twelve organs

You could switch from one organ to another to experience different styles, or you could just stay seated at this one. The American Classic 770 has three different organ styles, romantic, symphonic and baroque; and in each style you can choose from one of four different variations. So with the American Classic 770, you have twelve different organs at your fingertips.



The feel and sound of a pipe organ

The American Classic 770 operates just like a conventional pipe organ. Without having to study a complicated user manual, you can use the built-in capture system to easily change the preprogrammed registration. Make full use of the resources provided by 111 ranks of sampled pipes. Let the Sifflet frolic in the choir, give the Sesquialtera a melody of pure silver, and don’t forget to unleash the powerful 32’ Subbass to roll through the church. Bask in the nuanced sounds of a pipe organ recreated by LiveTune technology.



Twelve unique reverbs

The last chord is approaching; just four more measures, then three, then two, then it’s there. You hold the last chord and then release. The reverb, which gracefully enhanced the sound throughout the performance, once again rolls through the hall. But was that a concert hall, a great cathedral, or an intimate chapel? With the ASR-12 reverb system, you can choose between twelve unique rooms.



More than just a church organ

Based on the revolutionary T9000 system developed by Johannus, the American Classic 770 is certainly a full-fledged church organ, but it is also much more than that. The American Classic 770 is the absolute realization of the American musical dream. Congratulations. You have met the king of instruments.
