Mics & Amplification

Amplifying your accordion is a very personal venture, based on your performance needs, environment and the accordion itself. Harmonik Instrument Microphones (made in Brazil) have revolutionized the industry standard of accordion amplification. As the North American distributor, petosa offers primarily Harmonik Microphone systems, cables and accessories as well as installation and service. Additionally, petosa offers an array of wireless kits, cables and amplifiers to meet all of your amplification needs. 

Custom Tuning

Accordions come in all sorts of shapes and sizes, as due their tuning configurations; one of the many reasons the instrument is so versatile. It is extremely important that an accordion tuner has many years of experience and expertise, and uses only proper techniques (no power tools). Tuning an accordion improperly can result in the complete degredation of the instrument, as the reeds are the 'engine' of the instrument. Whether you are looking for spot tuning to bring your accordion back to factory spec, custom tuning to meet the needs of your music, or complete repitching of the instrument; we do it all. Nobody in North America has more combined experience than petosa accordions. 

Keyboard Action

When you buy your accordion from a retailer or factory, rarely is it discussed that treble key depth, pressure and play are adjustable to your playing style or preference. As a producer of the world's most premium accordions, we offer these detailed customizations tailored to our customer's exact requirements. If you find your keyboard to be too slow, too deep, too light, too stiff, etc... we can adjust spring tension, guide play, depth and more to ensure the feel and performance is exactly the way you want it. 

Bellows Lining

If accordion bellows are made well, they should last many decades without issue. If the bellow linings begin to show signs of wear and need to be replaced, we can remove the old lining and install new lining, ensuring your bellows the long life they deserve. We also offer custom bellow tape designs and colors, limited to available materials. 

Hardware

Don't underestimate the importance of your accordion's hardware. The quality of hardware and installation is key to the instrument's security while playing and compression integrity. Many manufacturers use wood screws over machine screws with internal washers and nuts to secure hardware, which are prone to stripping and breaking. If you'd like to upgrade your accordions hardware to a better, more secure system, we can help you. We also offer a wide variety of hardware shapes, sizes, orientation, colors and repair.  

Accessories

Changing the accessories on your accordion can be a fun and easy way to add your own personal touch to your instrument. We source only the finest American and Italian-made cases, covers, shoulder/bass straps, back pads, bellow fasteners and more. We offer many sizes and custom attachments such as backstraps in order to tailor the fit of your accordion perfectly.
