"ESTECHO’s music relies on many old and capricious musical instruments and devices. Keeping them in working condition is often a challenge, and for many of them, operation, maintenance and servicing information is very hard to come by. Often, pages such as this one are the only source of info available, pre-internet manufacturers having long since gone out of business or simply not remembering ever having these products for sale. For this reason, we’ve decided to share tips, tricks and info we’ve gathered while using, maintaining and repairing such devices."
