hey gang. old thread, i know. just sent a PM to strat8ohm, altho it looks like he's not been active. i'm working on a sustainer guitar and curious about his experience chopping the fernandes humbucker in half. anyone know what happened and/or done that before?

overclock-
Hello and welcome to G-nutz2!
Nothing further from strat8ohm, I'm afraid. But others here may be able to help if you have specific questions.

OK, I got some result with an sm57 transformer, After testing some wiring, i got some signal boost, but still not having enough level matching... with the neck p.u. gain trimmer maxed i´m got almost the same output of the midle pickup but sill kinda weak and there´s some treble loss... anyway, it shows that there some fix to this problem... i just need to find a tranformer with the right ratio, or close as possible... I know that this problem was investigated many years back, most likely in the old defunct and closed "Sustainer Idea's" thread over at PG. but the info is still there some where. Someone was able to identify it from the codes. However, if fernandes is offering a total replacement at $60 that's most likely the best and most efficient way of going if the driver/pickup is ok IMHO. The driver is a very low impedance pickup and the use of a transformer to boost such devices is fairly common, such as in teh Alumitone's by Lace, which have effectively only one turn in the coil of their frames, there is a transformer below that is bringing that extremely low impedance signal up to run passively. In my sustainer designs, I st out for the things to go off completely when not in use and maintain the passive nature of the guitar and to prolong battery life and other issues. On the commecial units, lose power (and these things drain a lot) and your whole guitar dies. I designed aroud the pickupas the driver by trying to make them smaller or combined (so a pickup with a driver coil on top say) so that there is no compromise between the chice of neck pickup and the driver...but that's a whole other story. Both the fernandes and sustainiac devices are excellent devices, all ahve their pro's and cons... EDIT: On the 'mix mode'...there are a few ways to bring out the harmonics. One that is typicall for the harmonics mode is to simply put the driver out of phase, a simple phase switch. This will suppress the fundamentals and driver the next strongest partials/harmonics on a given fret (they are not usually octaves) relative to the driver and pickup positions. Another way is like a 'tone control)...a little different but all the same...if the amplifier is biased towards the higher frequencies it will often drive the higher harmonics instead of the fundamentals...my sustainers tend to have this on the low notes as a standard. So, there is a 'mix' where some notes will come out as harmonics, often bloom beautifully between the notes sounded and fade to a harmonic, this is the principle in which 'Mix' controls work, in fact sustainiac had/has a mix knob to make things more selectable and while I was working with the sustainers got the chance to play such a guitar and it was quite an impressive control. hi, I'm new to this board and am in dire need of help, if I could get any info on this it would be very helpful, I have an old fernandes sustainer unit from 95 and can't find an accurate wiring diagram, it's the fernandes 1.2 v bass sustainer, and the company itself will not even respond to me with any info, any info from you guys would be sweet

Similar problem here...
I am looking for the wiring diagram for the sustainer circuit from the early 90s. PCB says "ver 1.1".
