this seems like it maybe cool but Im a total new guy to mod ideaswww.projectguitar.com/tut/sustainer.htm

Interesting. I've got some LM386 chips at home too. Problem is, they suck batteries dry real fast. They have like a 40mA current draw.

This is one of those ideas that seems good but has some built in limitations. The idea seems to be to feedback the signal to the neck pickup by coupling it acoustically to the transducer, but this won't have any effect on the ongoing sustain of the string...
But it's amazing what works sometimes. A few years ago someone produced a device for reducing ski vibration by feeding an inverted signal from a transducer in the ski to an electrically sensitive piezo layer. Seemed flawed like perpetual motion but damn me if it didn't work like a dream! Be interesting to see if it works. I'm betting it just produces uncontrollable feedback.

Are you talking about the K2 skis where the little light turns on?

I didn't find them to be overly amazing.

If anybody's tried this, I'm interested in it as well. might be kindof a cool mod for one of my axes...

I don't know; I just remember seeing it on a TV programme about new inventions.
It reminded me of the Arthur C Clarke story about a guy who invents a box that cancels sound. It's a mike/amp/speaker combination which picks up sound, then puts out an inverted signal that makes everything go silent. In the end it explodes because the sound energy has to go somewhere and of course it goes into the box until it overloads.

I scoffed, obviously, because that kind of absolute cancellation can't work in reality in an acoustic environment, can it?

Then a car manufacturer (Ferrari, I think) used the exact same principle to reduce engine noise in the the car's interior...

Sound cancellation technology is in use as we speak. There are headphones that pilots wear that are noise cancelling. They take the extraneous noise and transmit it out of phase so that you don't hear anything except the intended signal. Humbucking pickups work on the same sort of principle.

Hi there...

Just came across this forum and checked out a search on sustainers...

While Ansil's Sustainer is in fact a bit (lot) dubious I can assure you that infinite sustain is possible and you may wish to check out this...

Let me introduce myself...I am psw from Project Guitar and quot;hostquot; of the sustainer thread.
This is one of those ideas that seems good but has some built in limitations. The idea seems to be to feedback the signal to the neck pickup by coupling it acoustically to the transducer, but this won't have any effect on the ongoing sustain of the string...

Hmmm...thems fighting words there...

I can assure you that infinite clean, ebow like sustain is possible in a DIY format...

This is my Sustainer Strat...Mod testing Guitar.And here's the driver/pickup taken apart...
It can be made also as a separate driver.

Basically it is as you describe, the same principle as Sustainiac or Fernandes Sustainer. The contribution I have made is to focus on driver design rather than complicated circuitry. All sustainers eat batteries I'm afraid...the circuit is a pre-amp/power amp and the driver is about 3mm thick and is the blue part of the above pickup. The circuit is very small and easy to make, as is the driver.

The above is unique in that it is a standard passive single coil that works as normal when the sustainer is off. Everyone else has made the driver as a separate device.

The LM386 circuit is just a simple and cheap solution to the circuit but I'm reviewing this with a view of getting a little more power out of it and better battery consumption. It is the nature of the beast that it will churn through batteries every week or so, but you can use a rechargable.

I have a new design in mind that includes the driver (a new design) and circuit (also new) in a humbucker package to kind of drop in...so more development is still to come.

As it is, it is a very do-able DIY project and a lot of fun to play. There are various sound bites...here's a link to some...just to show it works...

Want a sustainer? Look here!

Yes...and your point is?

I just thought that member's here may be interested in DIY sustianers as origonally posted. Fernandes also makes a good commercial system but both require a fair bit of instalation and are a little pricey...hope other's find the post of use...
