Ok... so sustainer's are still a sensitive subject. Until I can get one built in January or February, let work towards something productive. OP has a driver, it doesn't work because of... oh, it was 'thrown together' without following the specs to the letter(to no fault of the OP btw just needed to obtain the right parts). SO even NOT built to specs and NOT following anyone's circuit, OP managed sustain on lower three strings using lights. How much does that tell you about the importance of the circuit vs coil specs? The HEART of the sustainer is the design pete has laid out, and he's made that clear. On the other hand, you need a circuit. Pete suggests a LM386, so let do it. This will start generic and can be modified as needed. Here is part one of the design, will this work?
Part two, will this work when connected to part one? (change 250uF to 100uF) gain=20x
I would please ask that further replies be restricted to design aspects from here on, or any other subjects not related to personal disputes. Topics such as sandy beaches, sustainer circuits, and puppies are OK.
