>> NEW!! We've just added the ESTECHO keyboards page

ESTECHO's music relies on many old, sometimes 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 hard to come by. Many times, pages such as this one are the only source of info available, because the manufacturer has long since gone out of business or simply doesn't even remember 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.
