Welcome to ESP, the home of DIY audio articles, projects and shortform kits. Audio is a wonderful hobby, and with DIY there is a huge scope to get the very best performance for a lot less money than otherwise. DIY audio is fun and educational, and by building your own audio equipment, you get to learn electronics as well as build equipment that would cost a great deal more in the shops. ESP is committed to providing high quality projects that are known to work, printed circuit boards (PCBs) for the most popular projects, and to assist you if necessary to complete or debug your project. There is a very wide range of power amplifiers, preamps, guitar/ bass amplifiers, studio equipment, effects, and other projects to build, including loudspeakers, subwoofers, and many others. Purchase PCBs to gain access to even more information.
