Classic PETOSA AM 1100 Accordion -  The Flagship Model!

Dear Accordion Friends,

This is a classic Petosa AM 1100 accordion, built in 1999 and still in excellent condition. This fabulous acoustic instrument comes with a factory installed S-2000 MIDI controller, fully programmed and ready to be used. This accordion has been a dream for a generation of American musicians. It features the famous Petosa mahogany chamber and solid walnut keyboard. The mechanics is indestructible. The tone is rich and powerful. With one set of bassoon reeds and three sets of clarinet reeds the instrument features both concert and musette sounds. (Please, note that the treble switches indicate piccolo reeds. The instrument was originally sold with interchangeable reed blocks fro LMMH and LMMM. The MH reed blocks were sold separately by the previous owner.) The 10 (!) bass switches would allow you to find the perfect balance between treble and bass for any selected reed combination. In addition to the excellent acoustic features, the accordion has built-in microphones and a full MIDI installation with very friendly grill controller. You can play this accordion as a fine acoustic instrument, as amplified accordion, as a MIDI instrument sounding like a full orchestra, or in any combination.

The accordion comes with a second "acoustic" grill, chrome plated and custom engraved. With this grill you can use the microphones but not the MIDI. It changes the appearance of the accordion. You can surprise your friends and audience as if you had two of these fine instruments.

The AM 1100 model features the best hand-made reeds available with double tone chamber from solid mahogany and low-A bass configuration.  It remains the flagship model of Petosa Accordions in Seattle.

I can't stress enough how important it is to have a professional programming in order to enjoy the electronics orchestral capabilities of a MIDI accordion. With a Solton MS40 or Ketron XD3 (available on request) you can control in real time not only the orchestral sounds but the rhythms and styles, alternate between different variations of a particular pattern, play along with MIDI files etc. Of course, you can use this accordion with any other MIDI module you choose. Here is a taste of what is possible with this instrument. Videos courtesy of Petosa Accordions:

The packages comes with the following accessories, already nicely interfaced and ready for real time performance:
The following (optional) MIDI modules/arranges are available for purchase with this accordion

This instrument is one of the best you can find. The tone is clear, yet rich and strong. Each reed combination has unique tonal color. The acoustic balance between treble and bass is excellent. The reeds are very efficient and allow for a great dynamic range. With the custom tuning you can play a huge variety of music and always enjoy an authentic sound - jazz, classical, ethnic, Italian, German. The orchestral capabilities of the MIDI will open a whole new universe for musical expression. It doesn't get any better!

Our children and grandchildren will still admire the craftsmanship and the tonal personality of the AM 1100. Yes, I am confident there is future for the accordion. The time of prejudice is gone. You can tell by the accordion music featured in many movies and recent TV commercials for American Express and BMW. Even the popular TV show "The price is right" featured an accordion recently, a Petosa accordion. I am very pleased to see many young talented musicians perform on the accordion.

I hope you enjoy the pictures below and would be glad to hear from you at 973-770-6877 with any questions.

The 4 knobs on the right side of the above picture (closer to your chin) control the volume of the electronic sounds (MIDI audio channels) - master, treble, bass, and chords. The 4 square buttons above the volume knobs allow for changing the variation of the selected style (both rhythm pattern as well as richness of accompaniment; fully programmed). The 3 knobs on the lower side of the grill (shown on the left in the above photograph) control the volume of the built in microphones - master, treble, and bass.

The profile of the palm master switch is very smart and helps avoid interference
with the performers right leg while sitting on a chair.

Please, note that the treble switches indicate piccolo reeds. The instrument was originally sold with
interchangeable reed blocks fro LMMH and LMMM. The MH reed blocks were sold separately by the previous owner.

The acoustic grill comes in a custom made padded box. The amplification can be used with that grill as well.

Depending on light angle the grill has different appearance and really captivates the audience.

The photograph below shows the "electronic" grill with the embedded MIDI controller.

The keyboard is perfectly aligned and calibrated. The valves are like new. You will play better on this instrument.

All cables and accessories are included, neatly stored in a custom made gig-bag with foam padding:

1. S-2000 module (serves as a tone generator and power supply (the black box with blue print)
2. Effects pedal board (connects to the S-2000 module with the black cable in the far right in the above photo)
3. MIDI data cable connecting the accordion to the S-2000 module (multi-pin connectors, see picture below)
4. General MIDI cable (in the middle, picture above) connecting the MIDI Out of the S-2000 to an external MIDI module
5. Stereo audio cable for the accordion microphones (connects to the accordion; bundled with the MIDI data cable)
6. Power cord

This instrument was built to last for generations of musicians. The interior is as nicely finished as the exterior.
All parts have been carefully selected and are in excellent condition - the keyboard valves, the reed leathers,
the wax, all mechanical assemblies... All metal components are anodized and will never corrode.
The reeds are fabulous and the response is truly impressive.
