Also, what about using an oscillator to drive the strings? Perhaps a low-frequency high-low duty cycle pulse wave would be a good way to actually generate string vibrations so that chords can be more easily sustained. The frequency would likely have to be lower than hearing range, but effectively it would be simulating a slight "picking" of the string indefinitely. Perhaps by low-passing the oscillator, there would be a minimum of interference between the string vibrations and the oscillations. -Mike

Hello Pete! First off, let me say - you are the man. I am as broke a college student as they come, except I'm studying electrical engineering at school (as sort of an unofficial minor). So I can actually have a sustainiac by building one. I'm going to put it in this guitar I just defretted - should be interesting. I don't want to sound lazy, but I started going through this thread and I can't even figure out what ideas have been tossed out and what the current "best way" is... Is there any "updated" version or step-by-step guide to doing this mod? Or, is there any direction you could point me in just to find which methods are currently known to work? I started reading from page 1, got to page 7, and gave up. Furthermore, I don't know if you've seen this, but Moog just came out with this guitar... http://www.moogmusic.com/moogguitar/?secti...roduct_id=21129 Pretty much equipped with a sustainiac * 1000. One thing I like about it a lot is that you can use the harmonic pedal to "pull" harmonics from the guitar. So here's my question: However the circuit is being driven, if you feed magnetically back into the strings the signal coming out of the pickup, that translates to sustain, right? Then, logically, if you feed the signal back in out of phase, that would give a sort of muted feel to the strings as well, si? And furthermore, if you were to pass the signal through an all-pass filter and screw with the phase response, you might be able to make a "harmonic" function like the Moog guitar has, right? I think I saw some clips from another thread in a faraway land where you posted sound clips of a harmonic function that you made for your sustainer mod... Is this how you did it? Trying to understand the basic concepts here. And lastly... If you took the signal from the pickup and fed it back in through a high-pass filter, would that make for a brighter, clearer tone? Perhaps accentuate the harmonics of the guitar? Similarly with a low pass filter, would that give a warmer, Pat Metheny-ish sound to it? These are some directions I see this mod going in, if someone hasn't done them already. Anyway, just some ideas, and if you have any links to any sort of "condensed" version of this thread, I'd appreciate it. I did find this link - http://www.storm-software.co.yu/diy/index....oject=sustainer. Is this "up-to-date" in terms of how this mod is most effectively approached? Thanks, Mike
