The professional tone chamber Sonola AA20 doesn't need a long description. Simply put, this is one of the best accordions you can find. This particular instrument is in very good to excellent condition. It has been serviced recently and is ready for a new home. It feels and sounds great. The compression is excellent. All reeds sound clear. All the hardware (bellows corners, grill ornaments, bellows metal-mesh straps, bass master switch, shoulder straps holders) is shiny. The accordion is very well balanced and easy to play for a long time. The reeds are very efficient and don't need much air to reveal their full dynamic range and tonal richness.  The response is fabulous. You will enjoy the beautiful blend and balance between treble and bass sound.
