Thanks the answers guys: about the split coil: The two coils are reverse wound to each other and they run into the same amplifier BUT between the + of the higher strings coil and the Kemo, there has to be a 220uF Capacitor. The Capacitor lets through only the higher frequencies and therefore this coil becomes optimized for the high strings. that's what he did. About PSW's it was not mi intention to criticise him in any way, i started this sustainer quest just recently and that thread it's the biggest and with more information in the entire web. Now i'm not an electronics guy, so i'm more on the side of having a little bit more of the work done. For example if the 386 it's not the best amp for this task, what should i use? Thinking about it, the amp it's just to make the coil move the strings, so technically any amp with enough power low comsumption and low distortion could do it..... right? So, for me it's making the fetzer/ruby or been in the complete dark, about the coil, of course there must be a relationship between the copper wire size, impedance of the coil and the strenght the coil has over the strings, but again i'm in the dark. If anyone can help me understand this things it would be much appreciated. in 2017 i will start studying an electronics course so in time everything gets easier. Thanks for the replys once again and sorry for my bad english.

HI!, i'm new in here, from uruguay. i'm in that same path that seems a lot of us is (was)... Diy sustainer!. Searching a lot on the internet, found the famous pete thread (and read a lot of it), but some other stuff too. So first there's the amp: everybody talks about the Fetzer/Ruby amp. so looking for that the most realiable thing i found was this: https://www.youtube.com/watch?v=md5aHzoegYs Now, that work only with 3 strings, the thinnest ones, on the thread the problem seems that there's not enough power for the six strings, so looking for that i found this: https://diysustainer.wordpress.com/dualcoil/ I couldn't understand much, but it seems that the solution was to make 2 coils that move 3 strings each, instead of making an amp he bought a kemo amplifier: https://www.kemo-electronic.de/en/Light-Sound/Amplifier-Splitter/Modules/M031N-Amplifier-3-5-W-universal.php that amp works from 4 to 16 ohm, so he made the coils disregarding of the impedance thanks to that amp. i want to make the amp: on the thread i found this picture: that sistainer picture was drawn by pete, he says that works but he couldn't test it, on the other hand, he says he make a circuit without the lm386 chip that works but never showed it. looking for other circuits i found this: https://www.youtube.com/watch?v=xXB92cSQi8E that guy says he made a completely different circuit that did not need the lm386 and also did not need that the coil be of 8 ohm (which accordingly to pete was a must). So: i'm gonna try to build this schematic that pete left and see what happens. first with 1 coil, and if that doesn't work, with 2 coils in one for 3 string each coil. i'm hoping that (maybe this) thread becomes the new sustainer thread (or making a new one), so we can have a (maybe) more organized way of making this work. Sorry if my english is not perfect. if anyone has any ideas or thoughts on this matter please share. Thanks all for all the info.
