How can I make a sustainer for an acoustic guitar (working on the principle of an e-Bow)?
I mentioned acoustic sustainer because I have been told it is easier to build than an electric sustainer. I have been told that piezos can be substituted for a normal mag p/up, then use a monophonic coil driver and the amp/preamp and AGC (Automatic Gain Control) to even string response. But I have had difficulties with the PG Sustainer thread instructions, particularly for acoustic guitar. There are various amplifier and preamplifier circuits available, but I am a complete novice to electronics. I have a more knowledgeable friend who is able to work from circuit diagrams, but I need to be very clear about what I want him to do, and need also to be able to access the components. Thanks in advance for your help.
