This is a fantastic Petosa-Organ accordion with the best hand made reeds available, double tone chamber, and excellent amplification and variety of electronic sounds. The instrument has been regularly played and maintained in perfect shape. It is very easy to install MIDI output to the tone generator while keeping the existing outputs. This way you can have the best of the acoustic and electronic sounds. The system is complete and ready for professional performance. You can have 4 separate channels for stereo amplified output, electronic sounds, or a combination of all.

All electronic features work without any electrical noise of problems. There are 5 preset combinations ready for you to enjoy. You can have wide variety of custom electronic sounds as well. The accordion can be played as an acoustic instrument, as an amplified accordion, as organ, or in any combination of electronic and reed sounds. The organ bass is excellent. The original organ on the treble is better than the modern midi arrangers because of the separate filters optimized for each octave. In the modern arrangers you have one filter for the whole keyboard range. Many of the new MIDI accordions are just average acoustic instruments with nice electronics. This instrument is one of the best acoustic accordions you can buy and you will appreciate this the minute you play your first chord. Yeas ago I had this model without chamber and really enjoyed it. I had a MIDI output card installed in the tone generator by Dave Henry at Syn-Cordion (Iorio) and it only cost me $200 at that time. This could be a nice upgrade to consider even if the price now is a little higher. I sold that non-chambered instrument to a good friend of mine who still loves it and plays it even more often than the expensive new instruments ($8000+) he bought after that. The Petosa family is still in business in Seattle. All people there are proud of each and every accordion they make and there is a reason for that. You just call them or even better, visit them and you will know what I mean.
