High Quality USA-made Straps by NeoTech. These ergonomically-designed straps are constructed of flexible neoprene padding and webbing with non-skid shoulder pad section to distribute weight and reduce strain. Very comfortable.

Neotech Pad-It straps

Pad-It Straps

A simple yet elegant strap that is sure to be a hit! The shoulder pads are made with an anti-microbial memory foam that conforms to the shoulders for a comfortable fit that makes even heavy instruments a breeze to wear. The pads also help to wick moisture away for additional comfort. The straps connect to the instrument with their unique loop connection system for added security. Length is adjustable from 33" to 51".

Neotech straps

Accordion Harness Straps

Ideal for small- to medium-sized accordions. These taper from 3" at the shoulder down to 2" and are length adjustable from 23" to 49". Includes their unique adjustable backstrap which quickly joins the two shoulder straps together with a quick disconnect for ease of use and helps to maintain the proper playing position.


Deluxe Accordion Harness

Another great option from Neotech for heavier accordions, where slightly less stretch is preferred. It's available in two sizes: Regular (pad size 2-1/4" wide x 21" long) and Junior (pad size 2" wide x 13" long). Its innovative new design combines a padded foam core, neoprene, and heavy elastic for a truly unique feel. The design incorporates a fully adjustable back strap that can be moved up and down the pad as well as adjusted across the back.

The Button Box stocks accordion and concertina microphones from Microvox, a small company in the United Kingdom specializing in mic systems for acoustic instruments. We also carry Microvox microphones for other instruments, including violin, viola, flute, whistle, bodhran, guitar, mandolin, bouzouki, brasses, and banjo. Microvox provides a three-year warranty on their products.

Microvox microphones use electret condenser mic elements. All are studio quality or better. Accordion and concertina microphones attach to the instrument with strips of Velcro, making installation simple and reversible, allowing for easy transfer of mics from one instrument to another, and providing some insulation from mechanical noise. See the Microvox FAQ for more information.

Accordion Microphones

The accordion treble microphone is a long bar with 3 or 4 microphone elements. Many players choose to mic the bass side of the accordion as well. Microvox makes two series for accordions: the M420/M410/M405 series, which requires a power supply unit; and the M305/M310 series, which is powered by an AA battery.

These units have their own built-in power supply and require only a AA battery. The treble bar has three mic elements and the output is a ¼" jack.
