PETOSA Chambertone Accordion with Guidobaldi Reeds and Harmonic Microphones

SOUND SAMPLES (headphone recommended)

Dear Accordion Friends,

This Petosa Chambertone accordion was built in 1954 and to this day remains a standard for quality in the Accordion World. The instrument has been played and loved over the years, professionally maintained by Petosa Accordions, and most recently serviced at the Accordion Gallery in July 2024. In 2019 I purchased 3 Chambertone models from the Petosa Family. Joe Petosa Sr. described this particular instrument very accurately: "Immaculate condition, this rich, resonant and powerful Chambertone is aged like a bottle of fine wine – a truly beautiful piece of history that any professional will appreciate."

This accordion has been a dream for a generation of American musicians. It features the famous Guidobaldi hand-made reeds. The bassoon and clarinet reeds are in a tone chamber. A second set of clarinet reeds and the piccolo reeds are outside of the chamber. With this classic LMMH reed configuration and double tone chamber this instrument is suitable for any music style. Harmonic condenser microphones complement this fine acoustic 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. You can play a large variety of music and always enjoy an authentic sound - jazz, classical, Balkan, Italian, German.

I hope you enjoy the pictures below and would be glad to hear from you at 973-219-9259 with any questions.

I serviced the keyboard in July 2024.

All valves are made of white natural felt and leather and are in very good condition. The keyboard action is fast and silent.

The keyboard is perfectly aligned and precisely calibrated for a light touch and fast response.

The original Guidobaldi reeds and genuine leather reed valves are in excellent condition. The reeds have never been abused by power tools.

The picture below is very informative. A trained eye of an accordion technician will immediately appreciate the precise voicing the the reeds.
The musicians will enjoy instant response and a stable pitch at various bellows pressure. The dynamic range (from soft to loud sound) is impressive.

Let's take a look inside the bass side...

This instrument was built to last for generations of musicians.
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.
